Single Non-transferable Vote
Single non-transferable vote or SNTV is a multi-winner electoral system in which each voter casts a single vote. Being a semi-proportional variant of first-past-the-post voting, under SNTV small parties, as well as large parties, have a chance to be represented. Under SNTV, a single party seldom will take all seats in a city or district, as generally happens with winner-take-all systems. Under certain conditions, such as perfect tactical voting, SNTV is equivalent to proportional representation by the D'Hondt method. SNTV is a combination of multi-member districts and each voter casting just one vote. SNTV can be considered a variant of dot voting where each voter has only one point to assign. It can also be seen as a variant of limited voting where each elector has one vote, or as a simple version of Single Transferable Voting where votes are not transferred. Unlike block voting or limited voting, where voters can cast multiple votes, under SNTV each voter casts just on ...

Semi-proportional Representation
Semi-proportional representation characterizes multi-winner electoral systems which allow representation of minorities, but are not intended to reflect the strength of the competing political forces in close proportion to the votes they receive. Semi-proportional voting systems are generally used as a compromise between complex and expensive but more-proportional representation, proportional systems (like the single transferable vote) and simple Winner-takes-all voting, winner-take-all systems. Examples of semi-proportional systems include the single non-transferable vote, limited voting, and parallel voting. Semi-proportional systems Most proportional representation systems will not yield precisely proportional outcomes due to the use of election thresholds, small electoral regions, or other implementation details that vary from one elected body to another. However, systems that yield results close to the ideal are generally considered fully-proportional. The choice to use a semi- ...

Plurality Block Voting
Plurality block voting is a type of block voting method for multi-winner elections. Each voter may cast as many votes as the number of seats to be filled. The candidates with the most votes are elected. The usual result when the candidates divide into parties is that the most-popular party in the district sees its full slate of candidates elected, even if the party does not have support of majority of the voters. The term plurality at-large is in common usage in elections for representative members of a body who are elected or appointed to represent the whole membership of the body (for example, a city, state or province, nation, club or association). Where the system is used in a territory divided into multi-member electoral districts the system is commonly referred to as "block voting" or the "bloc vote". These systems are usually based on a single round of voting. The party-list version of block voting is party block voting (PBV), also called the general ticket, which also ...

Tactical Voting
Strategic or tactical voting is voting in consideration of possible ballots cast by other voters in order to maximize one's satisfaction with the election's results. Gibbard's theorem shows that no voting system has a single "always-best" strategy, i.e. one that always maximizes a voter's satisfaction with the result, regardless of other voters' ballots. This implies all voting systems can sometimes encourage voters to strategize. However, weaker guarantees can be shown under stronger conditions. Examples include one-dimensional preferences (where the median rule is strategyproof) and dichotomous preferences (where approval or score voting are strategyproof). With large electoral districts, party list methods tend to be difficult to manipulate in the absence of an electoral threshold. However, biased apportionment methods can create opportunities for strategic voting, as can small electoral districts (e.g. those used most often with the single transferable vote). Proporti ...

Proportional Representation
Proportional representation (PR) refers to any electoral system under which subgroups of an electorate are reflected proportionately in the elected body. The concept applies mainly to political divisions (Political party, political parties) among voters. The aim of such systems is that all votes cast contribute to the result so that each representative in an assembly is mandated by a roughly equal number of voters, and therefore all votes have equal weight. Under other election systems, a bare Plurality (voting), plurality or a scant majority in a district are all that are used to elect a member or group of members. PR systems provide balanced representation to different factions, usually defined by parties, reflecting how votes were cast. Where only a choice of parties is allowed, the seats are allocated to parties in proportion to the vote tally or ''vote share'' each party receives. Exact proportionality is never achieved under PR systems, except by chance. The use of elector ...

Wasted Vote Effect
In electoral systems, a wasted vote is any vote cast that is not "used" to elect a winner, and so is not represented in the outcome. However, the term is vague and ill-defined, having been used to refer to a wide variety of unrelated concepts and metrics. The analysis depends on the way a "wasted vote" is defined. Wasted votes seldom affect each party equally irrespective of the system that produces them. More wasted votes for one party and fewer for another create a disproportionate chamber of elected members. Distortions produced by wasted votes work against the aim of fairly reflecting the wishes of the electorate. However, a system that produces wasted votes may prevent instability caused by many parties being elected to the legislature. Terminology There are at least two different types of wasted votes: Wasted votes and efficiency gap are defined pp. 850–852. * Lost votes are votes that make no impact on which candidates are elected. These votes do not actually elect ...

Split Vote
A split vote is normally used synonymously with "deadlocked", "hung", or "evenly split" vote. It indicates a vote in which no decision can be made, as neither side has the majority. The term can be used to indicate dissent by as little as a single vote, if a unanimous vote is required. If a casting vote is available, this may be used to break the deadlock. In other cases it may result in situations such as hung juries or hung parliaments. A split vote may arise from vote splitting, which occurs in an election when the existence of two or more similar candidates reduces the votes received by each of them, reducing the chances of any one of them winning against another, significantly different, candidate. In systems that require a winning candidate to receive a majority of votes, this may result in a runoff election The two-round system (TRS or 2RS), sometimes called ballotage, top-two runoff, or two-round plurality, is a single-winner electoral system which aims to elect a m ...

Strategic Nomination
Strategic nomination refers to the entry of a candidate into an election with the intention of changing the ranking of other candidates. The name is an echo of ‘tactical voting’ and is intended to imply that it is the candidates rather than the voters who are seeking to manipulate the result in a manner unfaithful to voters’ true preferences. The same effect may occur even if candidates are not nominated with this thought in mind. Depending on the voting system being used, the addition of extra candidates with similar constituencies may either split away votes and hurt their combined prospects (in plurality voting systems), or it may concentrate votes in favor of the overrepresented constituencies (in positional voting systems). Strategic nomination may also be employed to confuse voters by running candidates with similar names to a major candidate. This can be seen as a type of vote-splitting, but could have some effect even in otherwise robust methods if some voters vote ...

First Past The Post
First-past-the-post (FPTP)—also called choose-one, first-preference plurality (FPP), or simply plurality—is a single-winner voting rule. Voters mark one candidate as their favorite, or First-preference votes, first-preference, and the candidate with more first-preference votes than any other candidate (a Plurality (voting), ''plurality'') is elected, even if they do not have more than half of votes (a ''majority''). FPP has been used to elect part of the House of Commons of the United Kingdom, British House of Commons since the Middle Ages before spreading throughout the British Empire. Throughout the 20th century, many countries that previously used FPP have abandoned it in favor of other electoral systems, including the former British colonies of Australia and New Zealand. FPP is still De jure, officially used in the majority of U.S. state, US states for most elections. However, the combination of Partisan primary, partisan primaries and a two-party system in these jurisd ...

2020 Vanuatuan General Election
General elections were held in Vanuatu on 19–20 March 2020. The elections were initially intended to be held on 19 March, but logistical problems resulted in some areas voting the following day. Electoral system The 52 members of Parliament were elected from eight single-member constituencies and ten multi-member constituencies (of between two and seven seats) by first-past-the-post and single non-transferable vote, respectively. Campaign The Vanua'aku Pati launched its campaign slogan 'Lets Rebuild Vanuatu' in June 2019 and endorsed the continuation of its Kambak ("come back") policy. In October 2019, a 'Vot Woman' campaign was launched, supporting all female candidates and calling for guaranteed 50% representation for women in parliament. No women were elected in the 2012 or 2016 elections. There were around 15 female candidates, but none were elected. The youngest woman candidate in 2020 was Litiana Kalsrap. An important issue was the future of the lucrative but controv ...

Droop Quota
In the study of Electoral system, electoral systems, the Droop quota (sometimes called the Eduard Hagenbach-Bischoff, Hagenbach-Bischoff, Britton, or Newland-Britton quota) is the Infimum, minimum number of votes a party or candidate needs to receive in a district to guarantee they will win at least one seat. Reprinted in ''Voting matters Issue 24'' (October 2007) pp. 7–46. The Droop quota is used to extend the concept of a majority to multiwinner elections, taking the place of the 50% bar in single-winner elections. Just as any candidate with more than half of all votes is guaranteed to be declared the winner in single-seat election, any candidate with more than a Droop quota's worth of votes is guaranteed to win a seat in a Multiwinner voting, multiwinner election. Besides establishing winners, the Droop quota is used to define the number of excess votes, i.e. votes not needed by a candidate who has been declared elected. In proportional electoral quota, quota-based syste ...
