About the election

The ruling National Regeneration Movement (MORENA) and its allies (see note 1) won an outright majority in both chambers of the Congress, winning 364 seats in the 500-member Chamber of Deputies and 83 seats in the 128-member Senate. The opposition coalition (see note 2) came second with a total of 128 and 41 seats respectively. The Citizens' Movement (MC), led by Mr. Dante Delgado, came in third place. Gender parity was maintained in both chambers.

The 2024 parliamentary elections (see note 3) were held in parallel with the presidential polls. Ms. Claudia Sheinbaum (MORENA), a close ally of the outgoing President, Andrés Manuel López Obrador, won the presidential elections and the highest number of votes. She promised to continue President Obrador’s social programmes and reforms. Ms. Sheinbaum is due to be sworn in as President on 1 October 2024, to become the first woman in Mexico to hold the presidency.

The 2024 elections were marred by violence: 38 candidates were killed during the campaign period. Multiple threats and two more murders were reported on polling day. The key electoral issues included: violence and insecurity, corruption, the continuation of social programmes, economic issues, and violence against women.

Note 1:
The ruling coalition, “Sigamos haciendo historia”, comprised MORENA (led by Mr. Mario Martín Delgado), the Ecologist Green Party of Mexico (PVEM, led by Ms. Karen Castrejón Trujillo), and the Labour Party (PT, led by Mr. Alberto Anaya Gutiérrez).

Note 2:
The coalition “Fuerza y Corazón por México” comprised the National Action Party (PAN, led by Mr. Marko Cortés Mendoza), the Institutional Revolutionary Party (PRI, led by Mr. Alejandro Moreno Cárdenas), and the Party of the Democratic Revolution (PRD, led by Mr. Jesús Zambrano Grijalva). It endorsed the Senator, Ms. Xóchitl Gálvez (PAN) as its presidential candidate. The three parties in the coalition reduced their share of seats in both chambers of the Congress. The PRD lost its national registration for not having obtained the requisite 3% of votes in the election.

Note 3:
The 2024 poll was the first general election after constitutional amendments were passed, which lowered the minimum eligibility age for the Chamber of Deputies from 21 to 18 years old. The amendments came into force in June 2023.
