Elections in Mexico

Voter eligibility Mexican citizens over 18 are eligible to vote in all Mexican elections. To carry the ballot, the citizen should first request a Voter Credential (), a plastic card issued by the National Electoral Institute (, INE) of the federal government. To receive a voter credential, citizens need: • Proof of either their birth in Mexico or their naturalization. • Some form of photo ID. • Proof of residence. Electoral system Mexico is a federal republic. The electoral system is regulated by the Constitution of Mexico and the constitutions of the 32 federative entities. These constitutions separate powers into three branches: executive, legislative, and judicial. The heads of the executive and all members of the legislature are open to election by the citizens. Officials of the judiciary were previously not open to election until the approval of the 2024 Mexican judicial reform. The first judicial elections will be held in 2025. The heads of government executive bodies are commonly directly elected by popular vote for a six-year term. Terms of elected executives are non-renewable, and seeking to be reelected is forbidden by the Constitution. The executive election is held through voting on a single plurality ballot for the candidate, and the winner is decided by first-past-the-post voting. The members of the legislatures are commonly directly elected by popular vote for a three-year (federal and local deputies) or a six-year (senators) term. There are usually term limits placed on legislative members (12 years at the federal level, not eligible for immediate re-election starting in 2030). All legislative elections have mixed electoral systems. The votes are counted toward candidates and political parties through one-ballot mixed single or two-ballot parallel voting. The winners are decided by a hybrid across first-past-the-post voting (single-member district), party-list proportional representation, and/or mixed-member proportional representation. Political parties Mexico has a multi-party system with three dominant political parties. Before 2000, Mexico had a system of one-party dominance under the Institutional Revolutionary Party and some smaller opposition parties. Alliances and coalitions are common. Usually, they are local (state) affairs and involve one of the big three and any number of minor parties, though, on extraordinary occasions, two of the big three will ally themselves against the third (e.g., the 2003 Colima state election or the 2004 Chihuahua state election). Indigenous communities Article 2 of the Constitution of Mexico provides for the self-government of indigenous communities according to their "traditional customs" (). This has resulted in several indigenous communities in Mexico maintaining local systems, notably those of Cherán and areas under Councils of Good Government control. == Federal elections ==

According to the Constitution of Mexico, several important officials of the federal government of Mexico ( or ) shall be elected by all Mexican citizens, including the president of Mexico, who serves as the head of state and head of government, all members of the bicameral Congress of the Union that consists of the Chamber of Deputies and the Senate of the Republic, as well as the top officials of the judiciary, including the Supreme Court of Justice of the Nation, along with other courts and tribunals. Under the current Mexican electoral system, the president of Mexico is directly elected for a six-year non-renewable term. The 128 senators are elected for a six-year term. The 500 deputies are elected for a three-year term. The elections are synchronized so that Mexican citizens elect the president, senators, and deputies at once every six years. A midterm election for deputies will occur at the midpoint of the six-year term. Federal elections are typically held on the first Sunday in June. The last general election for president, the Senate, and the Chamber of Deputies was held on 2 June 2024. The next Chamber of Deputies election is expected in 2027, while the next presidential and Senate elections are scheduled for 2030. Following the 2024 judicial reform, the first judicial elections took place on 1 June 2025, with subsequent elections also planned for 2027. Presidential elections The president of Mexico () is elected for a six-year term by direct election of all Mexican citizens. The candidate who wins a plurality of votes is elected president. No president can serve more than a single term in office. Therefore, every presidential election in Mexico is a non-incumbent election. Congressional elections The Congress of the Union () comprises two chambers: the Chamber of Deputies and the Senate of the Republic. Chamber of Deputies elections The Chamber of Deputies () has 500 deputies (). The deputies are elected to a three-year term through a two-ballot parallel voting system. They may serve up to four consecutive terms (non-consecutive starting in 2030). Judicial elections == State and Mexico City elections ==

Mexico has 32 federative entities (), including 31 states and Mexico City. Each federative entity elects its head of the executive (governor or head of government) and all legislative members (congress). Gubernatorial and head of government elections The leader of a federative entity is officially named governor () for a Mexican state and head of government () for Mexico City. These officials are elected for a six-year non-renewable term by the citizens of that federative entity. To be a governor or head of government: • Candidates born in the federative entity must have been residents for three years before the election. • Candidates born outside the federative entity must have been residents for five years before the election. • Candidates must be at least 30 years old. • Candidates cannot have been a minister of any religion for five years before the election. • Candidates cannot have been in the military or a head of public security forces for 90 days before the election. • Candidates cannot have citizenship in any country other than Mexico. Congressional elections Each federative entity has a unicameral legislature officially named Congress (). Members of the congresses are called deputies (). All seats of the Congress are elected to three-year terms in a mixed electoral system. Deputies can serve up to four consecutive terms (non-consecutive starting in 2030). For example, there are 75 seats in the Congress of the State of México. Forty-five seats are apportioned in direct elections in single-member districts, and 30 are apportioned via proportional appointments. Political parties nominate their candidates for proportional appointments before the election. For a party to be eligible for proportional-appointment seats, it must run candidates in at least 30 districts and receive at least 3% of the vote throughout the state. Similar to the federal Chamber of Deputies, a party cannot have more than 8% of the seats in the legislature above its percentage of statewide votes (e.g., to win 50% of the legislative seats, a party must win at least 42% of the vote statewide) unless that excess was earned in the direct elections. To be a deputy of the Congress: • Candidates born in the federative entity must have been residents for one year before the election. • Candidates born outside the federative entity must have been residents for three years before the election. • Candidates must be at least 21 years old. • Candidates cannot have been a minister of any religion for five years before the election. • Candidates cannot have worked for any election commission for two years before the election. • Candidates cannot have been a sitting municipal or federal legislator for 90 days before the election. • Candidates cannot have been a sitting judge for 90 days before the election. • Candidates cannot have been in the military or a head of public security forces for 90 days before the election. • Candidates cannot be a sitting governor. == Municipal and borough elections ==

Under the current administrative divisions of Mexico, states are divided into municipalities, and Mexico City is divided into boroughs. The autonomy of these divisions is protected by the Constitution of Mexico. Leaders of these divisions, called municipal presidents () or borough mayors (), are directly elected for a three-year once-renewable term (non-consecutive starting in 2030). As of March 2024, there are 2,461 municipalities and 16 boroughs, constituting 2,477 electoral territorial units. == Schedule ==
