Mexico is organized as a federal presidential representative democratic republic. This means the government represents the United Mexican States through a system of shared power. The federal government is divided into three distinct branches. The executive branch is led by the President of Mexico. The President serves as both the head of state and the head of government. This leader is advised by a cabinet of secretaries. This cabinet remains independent from the legislature.

The legislative branch is known as the Congress of the Union. It is a two-chamber legislature. It consists of the Senate of the Republic and the Chamber of Deputies. The third branch is the judicial branch. This branch exercises judicial power through several different groups. These include the Supreme Court of Justice of the Nation. It also includes the Council of the Federal Judiciary. Other parts include collegiate, unitary, and district tribunals. All these branches were established by the Political Constitution of 1917.

Mexican politics changed greatly during the twentieth century. The Mexican Revolution took place between 1910 and 1920. This revolution followed the end of Porfirio Díaz's dictatorship. In 1920, a general named Alvaro Obregón overthrew the government. He became President of Mexico. He was later replaced by Plutarco Elías Calles, who ruled from 1924 to 1928. After Obregón was assassinated in 1928, a political crisis occurred. To create stability, Calles founded the Partido Nacional Revolucionario, or PNR. This was meant to help manage the transition between different presidents.

The political landscape shifted again under President Lázaro Cárdenas from 1934 to 1940. During his time, the party became the Partido de la Revolución Mexicana, or PRM. This party was organized on a corporate basis. It had specific divisions for peasants, labor, the popular sector, and the military. The PRM acted as an extension of the Mexican state. In 1946, the party transformed into the Institutional Revolutionary Party, known as the PRI. At this stage, the army was no longer a specific sector of the party. The government also nationalized the oil industry and redistributed land to peasants.

For many years, the PRI held almost hegemonic power. This means they had dominant control over the state and federal levels. However, people began to protest this authoritarian rule. In the late 1960s and early 1970s, students and left-wing groups held many protests. This tension led to the Tlatelolco Massacre in 1968. During this event, hundreds of protesters were killed. In 1988, the election of Carlos Salinas de Gortari was called fraudulent. This election was a turning point for the country. In 1989, members of the PRI formed the Party of the Democratic Revolution, or PRD, to challenge the leadership.

To build public confidence, Mexico moved toward a democratic transition. In 1990, the government created the Instituto Federal Electoral, or IFE. This took election administration away from the Ministry of the Interior. The IFE was later replaced by the Instituto Nacional Electoral, or INE. The INE is an autonomous institution. It organizes and oversees all federal electoral processes. Today, all political parties must register with the INE. They must also obtain at least 3% of the votes in federal elections to keep their registration.

Several major parties have shaped modern Mexico. The PRI dominated for over 70 years. The National Action Party, or PAN, was founded in 1939. The PAN won its first presidential municipality in 1947. In 2000, the PAN won the presidency, which was the first non-PRI president since 1929.

The PRD emerged as a third force after the 1988 elections. More recently, the National Regeneration Movement, or Morena, was founded in 2014. Morena won the elections in 2018 and 2024. While some citizens still distrust official results, many believe the system is fairer now.

Voting rules in Mexico are very specific. Suffrage is universal, free, secret, and direct. It is also compulsory for citizens aged 18 or older. There is no need for pre-registration because the identity document serves as a voting card. Presidential elections are held every six years. The President's term was recently changed from six years to five years and ten months. Legislative elections for the Senate happen every six years. The Chamber of Deputies is renewed every three years. These rules ensure that the people can participate in their democracy.
