2024 Mexican Senate election

Elections to the Senate of Mexico were held on 2 June 2024 as part of the 2024 general election, with all 128 Senate seats up for election. The winners will be elected for six-year terms to serve in the 66th and 67th Congresses (1 September 2024 to 31 August 2030). Those elected for the first time will be eligible for re-election in the 2030 general election.

In the 2018 election, the National Regeneration Movement (Morena) secured a plurality of seats. Along with their coalition, Juntos Haremos Historia, they achieved a majority. The successor coalition, Sigamos Haciendo Historia, is defending seventy seats in these elections.

Electoral system
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 and the remaining 32 are elected in a single nationwide constituency by proportional representation. 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).

The absolute majority (50%+1) is 65 seats and the supermajority (2/3) is 85 seats.

If legislators are absent at any voting section, the majority required for the approbation of laws (50+1) or Constitutional changes (2-thirds) will be proportional to the members present.

Sigamos Haciendo Historia
Sigamos Haciendo Historia ("Let's Keep Making History") is the left-wing coalition comprising the National Regeneration Movement (MORENA), the Labor Party (PT) and the Ecologist Green Party of Mexico (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
Fuerza y Corazón por México ("Strength and Heart for Mexico") is the opposition coalition, a big tent composed of the National Action Party (PAN), the Institutional Revolutionary Party (PRI) and the Party of the Democratic Revolution (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.

Candidates
The candidates contending in each state are listed below and can be found on the website of the National Electoral Institute (INE).

Senators-at-large
An additional 32 senators-at-large will be elected from nationwide lists drawn up by the parties, with the winners allocated among them in proportion to their share of the national vote in the Senate election. The party lists can be found on the website of the National Electoral Institute.
