Background

Procedure

The 128 members of the Senate are elected by two methods: 96 are elected in 32 three-seat constituencies based on the country's

states State most commonly refers to: * State (polity), a centralized political organization that regulates law and society within a territory **Sovereign state, a sovereign polity in international law, commonly referred to as a country **Nation state, a ...

and the remaining 32 are elected in a single nationwide constituency by

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) amon ...

. In the three-seat constituencies, two seats are allocated to the party receiving the highest number of votes (''mayoría relativa'') and one seat to the party receiving the second-highest number of votes (''primera minoría''). Senators are elected for six-year terms and will serve in the 66th and 67th Congresses.

Parties and coalitions

''Sigamos Haciendo Historia''

'' Sigamos Haciendo Historia'' ("Let's Keep Making History") is the left-wing coalition comprising the

(MORENA), the Labor Party (PT) and the

(PVEM). The coalition will field common candidates for the Senate in all states except Baja California, Chiapas, Guerrero, Hidalgo, Oaxaca, Querétaro, San Luis Potosí, Sinaloa, Sonora, Tabasco, Tamaulipas and Tlaxcala. In some of those states, the decision was not due to a breakdown in negotiations but was based on calculations that the parties could take both the first and second places, thus securing a clean sweep of three seats for the coalition.

''Fuerza y Corazón por México''

'' ("Strength and Heart for Mexico") is the opposition coalition, a

composed of the National Action Party (PAN), the

(PRI) and the

(PRD). The coalition will field common candidates for the Senate in all states except Guanajuato and Oaxaca.

Citizens' Movement

In a shift of strategy from the 2012 election (when it allied itself with the PRD and the PT) and the 2018 election (when it joined forces with the PAN and the PRD), the Citizens' Movement party (MC) declined to join either coalition and went into the elections on its own, including the Senate elections in all 32 states.
