The politics of Mexico function within the framework of a federal presidential representative democratic republic whose government is based on a multi-party congressional system, where the President of Mexico is both head of state and head of government. The federal government represents the United Mexican States. It is divided into three branches: executive, legislative, and judicial, established by the Political Constitution of the United Mexican States, published in 1917. The constituent states of the federation must also have a republican government based on a congressional system established by their respective constitutions.
The Institutional Revolutionary Party is a political party in Mexico that was founded in 1929 as the National Revolutionary Party, then as the Party of the Mexican Revolution and finally as the PRI beginning in 1946.

The Party of the Democratic Revolution is a state-level social democratic political party in Mexico. The PRD originated from the Democratic Current, a political faction formed in 1986 from the Institutional Revolutionary Party (PRI).

This sparked a movement away from the PRI's authoritarian rule.

The president of Mexico, officially the president of the United Mexican States, is the head of state and head of government of Mexico. Under the Constitution of Mexico, the president heads the executive branch of the federal government and is the commander in chief of the Mexican Armed Forces. The office, which was first established by the federal Constitution of 1824, is currently held by Claudia Sheinbaum, who was sworn-in on October 1, 2024. The office of the president is considered to be revolutionary, in the sense that the powers of office are derived from the Revolutionary Constitution of 1917. Another legacy of the Mexican Revolution is the Constitution's ban on re-election. Mexican presidents are limited to a single six-year term, called a sexenio. No one who has held the post, even on a caretaker basis, is allowed to run or serve again. The constitution and the office of the president closely follow the presidential system of government.
