Early American period

and Utah. The even more lightly populated and arid lower region of old Baja California remained as a part of Mexico. In 1846, the total settler population of the western part of the old Alta California had been estimated to be no more than 8,000, plus about 100,000 Native Americans, down from about 300,000 before Hispanic settlement in 1769. In 1848, only one week before the official American annexation of the area, gold was discovered in California, this being an event which was to forever alter both the state's demographics and its finances. Soon afterward, a massive influx of immigration into the area resulted, as prospectors and miners arrived by the thousands. The population burgeoned with United States citizens, Europeans, Chinese and other immigrants during the great

, California became a free state and September9 a state holiday. During the American Civil War (1861–1865), California sent gold shipments eastward to Washington in support of the Union. However, due to the existence of a large contingent of pro-South sympathizers within the state, the state was not able to muster any full military regiments to send eastwards to officially serve in the Union war effort. Still, several smaller military units within the Union army were unofficially associated with the state of California, such as the "California 100 Company", due to a majority of their members being from California. At the time of California's admission into the Union, travel between California and the rest of the continental United States had been a time-consuming and dangerous feat. Nineteen years later, and seven years after it was greenlighted by President Lincoln, the First transcontinental railroad was completed in 1869. California was then reachable from the eastern States in a week's time. Much of the state was extremely well suited to fruit cultivation and agriculture in general. Vast expanses of wheat, other cereal crops, vegetable crops, cotton, and nut and fruit trees were grown (including oranges in Southern California), and the foundation was laid for the state's prodigious agricultural production in the Central Valley and elsewhere. In the nineteenth century, a large number of migrants from China traveled to the state as part of the Gold Rush or to seek work. Even though the Chinese proved indispensable in building the transcontinental railroad from California to Utah, perceived job competition with the Chinese led to anti-Chinese riots in the state, and eventually the US ended migration from China partially as a response to pressure from California with the 1882
Chinese Exclusion Act The Chinese Exclusion Act was a United States federal law signed by President Chester A. Arthur on May 6, 1882, prohibiting all immigration of Chinese laborers for 10 years. The law excluded merchants, teachers, students, travelers, and diplo ...

California Genocide

Under earlier Spanish and Mexican rule, California's original native population had precipitously declined, above all, from Eurasian diseases to which the indigenous people of California had not yet developed a natural immunity. Under its new American administration, California's harsh governmental policies towards its own indigenous people did not improve. As in other American states, many of the native inhabitants were soon forcibly removed from their lands by incoming American settlers such as miners, ranchers, and farmers. Although California had entered the American union as a free state, the "loitering or orphaned Indians" were de facto enslaved by their new Anglo-American masters under the 1853 ''
Act for the Government and Protection of Indians The Act for the Government and Protection of Indians (Chapter 133, Cal. Stats., April 22, 1850), nicknamed the Indian Indenture Act was enacted by the first session of the California State Legislature and signed into law by the 1st Governor of Ca ...
''. There were also massacres in which hundreds of indigenous people were killed. Between 1850 and 1860, the California state government paid around 1.5million dollars (some 250,000 of which was reimbursed by the federal government) to hire militias whose purpose was to protect settlers from the indigenous populations. In later decades, the native population was placed in reservations and rancherias, which were often small and isolated and without enough natural resources or funding from the government to sustain the populations living on them. As a result, the rise of California was a calamity for the native inhabitants. Several scholars and Native American activists, including Benjamin Madley and

1900–present

In the twentieth century, thousands of Japanese people migrated to the US and California specifically to attempt to purchase and own land in the state. However, the state in 1913 passed the Alien Land Act, excluding Asian immigrants from owning land. During World War II, Japanese Americans in California were interned in concentration camps such as at Tule Lake and Manzanar. In 2020, California officially apologized for this internment. Migration to California accelerated during the early 20th century with the completion of major transcontinental highways like the

Divided in two by the Sacramento-San Joaquin River Delta, the northern portion, the Sacramento Valley serves as the watershed of the Sacramento River, while the southern portion, the San Joaquin Valley is the watershed for the San Joaquin River. Both valleys derive their names from the rivers that flow through them. With dredging, the Sacramento and the San Joaquin Rivers have remained deep enough for several inland cities to be seaports. The Sacramento-San Joaquin River Delta is a critical water supply hub for the state. Water is diverted from the delta and through an extensive network of pumps and canals that traverse nearly the length of the state, to the Central Valley and the State Water Projects and other needs. Water from the Delta provides drinking water for nearly 23million people, almost two-thirds of the state's population as well as water for farmers on the west side of the San Joaquin Valley.

In terms of total numbers, California has the largest population of White Americans in the United States, an estimated 22,200,000 residents. The state has the 5th largest population of African Americans in the United States, an estimated 2,250,000 residents. California's Asian American population is estimated at 4.4million, constituting a third of the nation's total. California's Native American population of 285,000 is the most of any state. According to estimates from 2011, California has the largest minority population in the United States by numbers, making up 60% of the state population.

California has historically been one of the most linguistically diverse areas in the world, with more than 70 indigenous languages derived from 64 root languages in six language families. A survey conducted between 2007 and 2009 identified 23 different indigenous languages among California farmworkers. All of California's indigenous languages are endangered, although there are now efforts toward language revitalization.The following are a list of the indigenous languages: Root languages of California: Athabaskan Family: Hupa, Mattole, Lassik, Wailaki, Sinkyone, Cahto, Tolowa, Nongatl, Wiyot, Chilula; Hokan Family: Pomo, Shasta, Karok, Chimiriko; Algonquian Family: Whilkut, Yurok; Yukian Family: Wappo; Penutian Family: Modok, Wintu, Nomlaki, Konkow, Maidu, Patwin, Nisenan, Miwok, Coast Miwok, Lake Miwok, Ohlone, Northern Valley Yokuts, Southern Valley Yokuts, Foothill Yokuts; Hokan Family: Esselen, Salinan, Chumash, Ipai, Tipai, Yuma, Halchichoma, Mohave; Uto-Aztecan Family: Mono Paiute, Monache, Owens Valley Paiute, Tubatulabal, Panamint Shoshone, Kawaisu, Kitanemuk, Tataviam, Gabrielino, Juaneno, Luiseno, Cuipeno, Cahuilla, Serrano, Chemehuevi As a result of the state's increasing diversity and migration from other areas across the country and around the globe, linguists began noticing a noteworthy set of emerging characteristics of spoken

Religion

The largest religious denominations by number of adherents as a percentage of California's population in 2014 were the Catholic Church with 28 percent, Evangelical Protestants with 20 percent, and Mainline Protestants with 10 percent. Together, all kinds of Protestants accounted for 32 percent. Those unaffiliated with any religion represented 27 percent of the population. The breakdown of other religions is 1% Muslim, 2% Hindu and 2% Buddhist. This is a change from 2008, when the population identified their religion with the Catholic Church with 31 percent; Evangelical Protestants with 18 percent; and Mainline Protestants with 14 percent. In 2008, those unaffiliated with any religion represented 21 percent of the population. The breakdown of other religions in 2008 was 0.5% Muslim, 1% Hindu and 2% Buddhist. The '' American Jewish Year Book'' placed the total Jewish population of California at about 1,194,190 in 2006. According to the

The first priests to come to California were Catholic missionaries from Spain. Catholics founded 21 missions along the California coast, as well as the cities of Los Angeles and San Francisco. California continues to have a large Catholic population due to the large numbers of Mexicans and Central Americans living within its borders. California has twelve dioceses and two archdioceses, the

The survey also revealed 48 percent of Californians say religion is "very important", compared to 56 percent nationally.

and Mexican influences. As a border and coastal state, Californian culture has been greatly influenced by several large immigrant populations, especially those from Latin America and Asia. California has long been a subject of interest in the public mind and has often been promoted by its boosters as a kind of paradise. In the early 20th century, fueled by the efforts of state and local boosters, many Americans saw the Golden State as an ideal resort destination, sunny and dry all year round with easy access to the ocean and mountains. In the 1960s, popular music groups such as The Beach Boys promoted the image of Californians as laid-back, tanned beach-goers. The California Gold Rush of the 1850s is still seen as a symbol of California's economic style, which tends to generate technology, social, entertainment, and economic fads and booms and related busts.

The five largest sectors of employment in California are trade, transportation, and utilities; government; professional and business services; education and health services; and leisure and hospitality. In output, the five largest sectors are financial services, followed by trade, transportation, and utilities; education and health services; government; and manufacturing. California has an unemployment rate of 3.9% . California's economy is dependent on trade and international related commerce accounts for about one-quarter of the state's economy. In 2008, California exported $144billion worth of goods, up from $134billion in 2007 and $127billion in 2006. Computers and electronic products are California's top export, accounting for 42 percent of all the state's exports in 2008. Agriculture is an important sector in California's economy. Farming-related sales more than quadrupled over the past three decades, from $7.3billion in 1974 to nearly $31billion in 2004. This increase has occurred despite a 15 percent decline in acreage devoted to farming during the period, and water supply suffering from chronic instability. Factors contributing to the growth in sales-per-acre include more intensive use of active farmlands and technological improvements in crop production. In 2008, California's 81,500 farms and ranches generated $36.2billion products revenue. In 2011, that number grew to $43.5billion products revenue. The Agriculture sector accounts for two percent of the state's GDP and employs around three percent of its total workforce.

In January 2011, California's total debt was at least $265billion. On June 27, 2013, Governor Jerry Brown signed a balanced budget (no deficit) for the state, its first in decades; however the state's debt remains at $132billion. With the passage of Proposition 30 in 2012 and Proposition 55 in 2016, California now levies a 13.3% maximum marginal income tax rate with ten tax brackets, ranging from 1% at the bottom tax bracket of $0 annual individual income to 13.3% for annual individual income over $1,000,000 (though the top brackets are only temporary until Proposition 55 expires at the end of 2030).

, giving California's cities a reputation for severe traffic congestion. Construction and maintenance of state roads and statewide transportation planning are primarily the responsibility of the California Department of Transportation, nicknamed "Caltrans". The rapidly growing population of the state is straining all of its transportation networks, and California has some of the worst roads in the United States. The Reason Foundation's 19th Annual Report on the Performance of State Highway Systems ranked California's highways the third-worst of any state, with Alaska second, and Rhode Island first. The state has been a pioneer in road construction. One of the state's more visible landmarks, the Golden Gate Bridge, was the List of longest suspension bridge spans, longest suspension bridge main span in the world at between 1937 (when it opened) and 1964. With its orange paint and panoramic views of the bay, this highway bridge is a popular tourist attraction and also accommodates pedestrians and bicyclists. The San Francisco–Oakland Bay Bridge (often abbreviated the "Bay Bridge"), completed in 1936, transports about 280,000 vehicles per day on two-decks. Its two sections meet at Yerba Buena Island through the world's largest diameter transportation bore tunnel, at wide by high. The Arroyo Seco Parkway, connecting Los Angeles and Pasadena, California, Pasadena, opened in 1940 as the first freeway in the Western United States. It was later extended south to the Four Level Interchange in downtown Los Angeles, regarded as the first stack interchange ever built. Los Angeles International Airport (LAX), World's busiest airports by passenger traffic, the 4th busiest airport in the world in 2018, and San Francisco International Airport (SFO), World's busiest airports by passenger traffic, the 25th busiest airport in the world in 2018, are major hubs for trans-Pacific and transcontinental traffic. There are about a dozen important commercial airports and many more general aviation List of airports in California, airports throughout the state. California also has several major seaports. The Port of Los Angeles and the Port of Long Beach in Southern California are the largest and second-largest seaports in the U.S., respectively, by volume of container cargo handled; as of 2018, collectively they handle 31.9% of all Twenty-foot equivalent unit, TEUs in the United States.Patrick Burnson

''Logistics Management'' (May 10, 2019).
The Port of Oakland and Port of Hueneme are the 10th and 26th largest seaports in the U.S., respectively, by number of TEUs handled. The California Highway Patrol is the largest statewide police agency in the United States in employment with more than 10,000 employees. They are responsible for providing any police-sanctioned service to anyone on California's state-maintained highways and on state property. By the end of 2021, 30,610,058 people in California held a California Department of Motor Vehicles-issued driver's licenses or Identity documents in the United States, state identification card, and there were 36,229,205 Vehicle registration, registered vehicles, including 25,643,076 automobiles, 853,368 motorcycles, 8,981,787 trucks and trailers, and 121,716 miscellaneous vehicles (including historical vehicles and farm equipment). Inter-city rail travel is provided by Amtrak California; the three routes, the ''Capitol Corridor'', ''Pacific Surfliner'', and ''San Joaquin (train), San Joaquin'', are funded by Caltrans. These services are the busiest intercity rail lines in the United States outside the Northeast Corridor and ridership is continuing to set records. The routes are becoming increasingly popular over flying, especially on the LAX-SFO route. Integrated Rapid transit, subway and light rail networks are found in Los Angeles (LACMTA, Metro Rail) and San Francisco (San Francisco Municipal Railway, MUNI Metro). Light rail systems are also found in San Jose (Santa Clara VTA Light-rail, VTA), San Diego (San Diego Trolley), Sacramento (Sacramento RT Light Rail, RT Light Rail), and Northern San Diego County (Sprinter (San Diego), Sprinter). Furthermore, commuter rail networks serve the San Francisco Bay Area (Altamont Corridor Express, ACE, Bay Area Rapid Transit, BART, Caltrain, Sonoma–Marin Area Rail Transit, SMART), Greater Los Angeles (Metrolink (Southern California), Metrolink), and San Diego County (Coaster (San Diego), Coaster). The California High-Speed Rail Authority was created in 1996 by the state to implement an extensive rail system. Construction was approved by the voters during the November 2008 general election, with the first phase of construction estimated to cost $64.2billion. Nearly all counties operate bus lines, and many cities operate their own city bus lines as well. Intercity bus travel is provided by Greyhound Lines, Greyhound, Megabus (North America), Megabus, and Amtrak Thruway Motorcoach.


Water

California's interconnected water system is the world's largest, managing over of water per year, centered on six main systems of aqueducts and infrastructure projects. Water use and conservation in California is a politically divisive issue, as the state experiences periodic droughts and has to balance the demands of its large agricultural and urban sectors, especially in the arid southern portion of the state. The state's widespread redistribution of water also invites the frequent scorn of environmentalists. The California Water Wars, a conflict between Los Angeles and the Owens Valley over water rights, is one of the most well-known examples of the struggle to secure adequate water supplies. Former California Governor Arnold Schwarzenegger said: "We've been in crisis for quite some time because we're now 38million people and not anymore 18million people like we were in the late 60s. So it developed into a battle between environmentalists and farmers and between the south and the north and between rural and urban. And everyone has been fighting for the last four decades about water."


Government and politics


State government

The capital city of California is
Sacramento ) , image_map = Sacramento County California Incorporated and Unincorporated areas Sacramento Highlighted.svg , mapsize = 250x200px , map_caption = Location within Sacramento ...
. The state is organized into three separation of powers, branches of government—the executive branch consisting of the Governor of California, governor and the other independently elected constitutional officers; the legislative branch consisting of the California State Assembly, Assembly and California State Senate, Senate; and the judicial branch consisting of the Supreme Court of California and lower courts. The state also allows California ballot proposition, ballot propositions: direct participation of the electorate by initiative, referendum, recall election, recall, and ratification. Before the passage of California Proposition 14 (2010), California allowed each political party to choose whether to have a closed primary or a primary where only party members and independent (politics), independents vote. After June 8, 2010, when Proposition 14 was approved, excepting only the United States president and county central committee offices, all candidates in the primary elections are listed on the ballot with their preferred party affiliation, but they are not the official nominee of that party. At the primary election, the two candidates with the top votes will advance to the general election regardless of party affiliation. If at a special primary election, one candidate receives more than 50% of all the votes cast, they are elected to fill the vacancy and no special general election will be held.


Judicial branch

California's legal system is explicitly based upon English common law but carries many features from Spanish Civil law (legal system), civil law, such as community property. California's prison population grew from 25,000 in 1980 to over 170,000 in 2007. Capital punishment in California, Capital punishment is a legal form of punishment and the state has the largest "Death Row" population in the country (though Oklahoma and Texas are far more active in carrying out executions). California has performed List of people executed in California, 13 executions since 1976, with the last being in 2006. California's judiciary system is the largest in the United States with a total of 1,600 judges (the federal system has only about 840). At the apex is the seven-member Supreme Court of California, while the California Courts of Appeal serve as the primary appellate courts and the California Superior Courts serve as the primary trial courts. Justices of the Supreme Court and Courts of Appeal are appointed by the governor, but are subject to retention by the electorate every 12 years. The administration of the state's court system is controlled by the Judicial Council of California, Judicial Council, composed of the chief justice of the California Supreme Court, 14 judicial officers, four representatives from the State Bar of California, and one member from each house of the state legislature. In fiscal year 2020–21, the state judiciary's 2,000 judicial officers and 18,000 judicial branch employees processed approximately 4.4 million cases.


Executive branch

The California executive branch consists of the governor and seven other elected constitutional officers: Lieutenant Governor of California, lieutenant governor, California Attorney General, attorney general, Secretary of State of California, secretary of state, California State Controller, state controller, California State Treasurer, state treasurer, California Insurance Commissioner, insurance commissioner, and California State Superintendent of Public Instruction, state superintendent of public instruction. They serve four-year terms and may be re-elected only once.


Legislative branch

The California State Legislature consists of a 40-member Senate and 80-member Assembly. Senators serve four-year terms and Assembly members two. Members of the Assembly are subject to term limits of six terms, and members of the Senate are subject to term limits of three terms.


Local government

California has an extensive system of local government that manages public functions throughout the state. Like most states, California is divided into County (United States), counties, of which there are 58 (including San Francisco) covering the entire state. Most urbanized areas are incorporated as city, cities, School districts, which are independent of cities and counties, handle public education. Many other functions, especially in unincorporated areas, are handled by Special-purpose district, special districts


Counties

California is divided into List of counties in California, 58 counties. Per Article 11, Section 1, of the Constitution of California, they are the legal subdivisions of the state. The county government provides countywide services such as law enforcement, jails, elections and voter registration, vital records, property assessment and records, tax collection, public health, health care, social services, libraries, flood control, fire protection, animal control, agricultural regulations, building inspections, ambulance services, and education departments in charge of maintaining statewide standards. In addition, the county serves as the local government for all unincorporated areas. Each county is governed by an elected board of supervisors.


City and town governments

Incorporated cities and towns in California are either Charter city, charter or general-law municipalities. General-law municipalities owe their existence to state law and are consequently governed by it; charter municipalities are governed by their own city or town charters. Municipalities incorporated in the 19th century tend to be charter municipalities. All ten of the state's most populous cities are charter cities. Most small cities have a Council–manager government, council–manager form of government, where the elected city council appoints a city manager to supervise the operations of the city. Some larger cities have a directly elected mayor who oversees the city government. In many council-manager cities, the city council selects one of its members as a mayor, sometimes rotating through the council membership—but this type of mayoral position is primarily ceremonial. The Government of San Francisco is the only consolidated city-county in California, where both the city and county governments have been merged into one unified jurisdiction.


School districts and special districts

About 1,102 school districts, independent of cities and counties, handle California's public education. California school districts may be organized as elementary districts, high school districts, unified school districts combining elementary and high school grades, or community college districts. There are about 3,400 special-purpose district, special districts in California. A Special-purpose district, special district, defined by California Government Code § 16271(d) as "any agency of the state for the local performance of governmental or proprietary functions within limited boundaries", provides a limited range of services within a defined geographic area. The geographic area of a special district can spread across multiple cities or counties, or could consist of only a portion of one. Most of California's special districts are ''single-purpose districts'', and provide one service.


Federal representation

The state of California sends California's congressional districts, 53 members to the United States House of Representatives, House of Representatives, the nation's largest congressional state delegation. Consequently, California also has the largest number of Electoral College (United States), electoral votes in national presidential elections, with 55. The current Speaker of the United States House of Representatives, speaker of the House of Representatives is the representative of California's 12th district, Nancy Pelosi; Kevin McCarthy (California politician), Kevin McCarthy, representing the state's 23rd district, is the Party leaders of the United States House of Representatives, House Minority Leader. California is represented by U.S. senators Dianne Feinstein, a native and former mayor of San Francisco, and Alex Padilla, a native and former secretary of state of California. Former U.S. senator Kamala Harris, a native, former district attorney from San Francisco, former attorney general of California, resigned on January 18, 2021, to assume her role as the current Vice President of the United States. In the 1992 United States Senate election in California, 1992 U.S. Senate election, California became the first state to elect a Senate delegation entirely composed of women, due to the victories of Feinstein and Barbara Boxer. Set to follow the Vice President-Elect, Gov. Gavin Newsom, Newsom appointed Secretary of State of California, Secretary of State Alex Padilla to finish the rest of Harris's term which ends in 2022 United States Senate election in California, 2022, Padilla has vowed to run for the full term in that election cycle. Padilla was sworn in on January 20, 2021, the same day as the Inauguration of President-Elect Joe Biden as well as Harris.


Armed forces

In California, , the U.S. Department of Defense had a total of 117,806 active duty servicemembers of which 88,370 were United States Navy, Sailors or United States Marine Corps, Marines, 18,339 were United States Air Force, Airmen, and 11,097 were United States Army, Soldiers, with 61,365 Department of Defense civilian employees.

was the largest origin of military recruits in the United States by county, with 1,437 individuals enlisting in the military. However, , Californians were relatively under-represented in the military as a proportion to its population. In 2000, California, had 2,569,340 veterans of United States military service: 504,010 served in World War II, 301,034 in the Korean War, 754,682 during the Vietnam War, and 278,003 during 1990–2000 (including the Persian Gulf War). , there were 1,942,775 veterans living in California, of which 1,457,875 served during a period of armed conflict, and just over four thousand served Interwar period, before World WarII (the largest population of this group of any state). California's military forces consist of the California National Guard, Army and Air National Guard, the California State Military Reserve, naval and state military reserve (militia), and the California Cadet Corps. On August 5, 1950, a Silverplate, nuclear-capable United States Air Force Boeing B-29 Superfortress bomber carrying a Mark 4 nuclear bomb, nuclear bomb crashed shortly after takeoff from Fairfield-Suisun Air Force Base. Brigadier General Robert F. Travis, command pilot of the bomber, was among the dead.


Ideology

California has an idiosyncratic political culture compared to the rest of the country, and is sometimes regarded as a trendsetter. In socio-cultural mores and national politics, Californians are perceived as more Modern liberalism in the United States, liberal than other Americans, especially those who live in the inland states. In the 2016 United States presidential election, California had the third highest percentage of Democratic votes behind Washington, D.C., the District of Columbia and Hawaii. In the 2020 United States presidential election#Results by state, 2020 United States presidential election, it had the 6th highest behind the District of Columbia, Vermont, Massachusetts, Maryland, and Hawaii. According to the Cook Political Report, California contains five of the 15 most Democratic congressional districts in the United States. Among the political idiosyncrasies, California was the second state California gubernatorial recall election, 2003, to recall their state governor (the first state being North Dakota in 1921 North Dakota gubernatorial recall election, 1921), the second state to legalize abortion, and the only state to ban marriage for gay couples twice by vote (including California Proposition 8, Proposition8 in 2008). Voters also passed California Proposition 71 (2004), Proposition 71 in 2004 to fund stem cell research, making California the Stem cell laws and policy in the United States#Legalization and funding, second state to legalize stem cell research after New Jersey, and California Proposition 14 (2010), Proposition 14 in 2010 to completely change the state's primary election process. California has also experienced California Water Wars, disputes over water rights; and a tax revolt, culminating with the passage of California Proposition 13 (1978), Proposition 13 in 1978, limiting state property taxes. California voters have rejected affirmative action on multiple occasions, most recently in November 2020. The state's trend towards the Democratic Party (United States), Democratic Party and away from the Republican Party (United States), Republican Party can be seen in state elections. From 1899 to 1939, California had Republican governors. Since 1990, California has generally elected Democratic candidates to federal, state and local offices, including current Governor Gavin Newsom; however, the state has elected Republican Governors, though many of its Republican Governors, such as Arnold Schwarzenegger, tend to be considered moderate Republicans and more Centrism, centrist than the national party. Several political movements have advocated for Partition and secession in California, Californian independence. The California National Party and the California Freedom Coalition both advocate for Californian independence along the lines of Progressivism in the United States, progressivism and civic nationalism. The Yes California movement attempted to organize an independence referendum via ballot initiative for 2019, which was then postponed. The Democrats also now hold a supermajority in both houses of the state legislature. There are 60 Democrats and 20 Republicans in the Assembly; and 29 Democrats and 11 Republicans in the Senate. The trend towards the Democratic Party is most obvious in presidential elections. From 1952 United States presidential election, 1952 through 1988 United States presidential election, 1988, California was a Republican leaning state, with the party carrying the state's electoral votes in nine of ten elections, with 1964 United States presidential election, 1964 as the exception. Southern California Republicans Richard Nixon and Ronald Reagan were both elected twice as the 37th and 40th U.S. Presidents, respectively. However, Democrats have won all of California's electoral votes for the last eight elections, starting in 1992 United States presidential election, 1992. In the United States House, the Democrats held a 34–19 edge in the CA delegation of the 110th United States Congress in 2007. As the result of gerrymandering, the districts in California were usually dominated by one or the other party, and few districts were considered competitive. In 2008, Californians passed Proposition 20 to empower a 14-member independent citizen commission to redraw districts for both local politicians and Congress. After the 2012 elections, when the new system took effect, Democrats gained four seats and held a 38–15 majority in the delegation. Following the 2018 United States House of Representatives elections, 2018 midterm House elections, Democrats won 46 out of 53 congressional house seats in California, leaving Republicans with seven. In general, Democratic strength is centered in the populous Coastal California, coastal regions of the Los Angeles metropolitan area and the San Francisco Bay Area. Republican strength is still greatest in eastern parts of the state. Orange County, California, Orange County had remained largely Republican until the 2016 and 2018 elections, in which a majority of the county's votes were cast for Democratic candidates. One study ranked Berkeley California, Berkeley, Oakland, California, Oakland, Inglewood and San Francisco in the top 20 most liberal American cities; and Bakersfield, California, Bakersfield, Orange, California, Orange, Escondido, California, Escondido, Garden Grove, California, Garden Grove, and Simi Valley, California, Simi Valley in the top 20 most conservative cities. In February 2021, out of the 25,166,581 people eligible to vote, 22,154,304 people were registered to vote. Of the people registered, the three largest registered groups were Democrats (10,228,144), Republicans (5,347,377), and Independent voter, No Party Preference (5,258,223).
