1946 Mexican general election

General elections were held in Mexico on 7 July 1946. The presidential elections were won by Miguel Alemán Valdés, who received 77.9% of the vote. In the Chamber of Deputies election, the Institutional Revolutionary Party won 141 of the 147 seats.

Background
With the establishment of the Federal Electoral Law of 1946, three political parties were registered: the National Action Party (PAN), the Mexican Democratic Party (PDM) and the Institutional Revolutionary Party (PRI), with the latter being a successor of the Party of the Mexican Revolution.

To better establish control over the various factions within the party, President Manuel Ávila Camacho sought greater worker discipline and strengthened the popular side of the party in the same year that he restructured the official one by eliminating the military sector, in order to prevent internal conflicts prior to voting as had occurred with Juan Andreu Almazán during the general elections of 1940.

Likewise, the PRI was experiencing a generational shift as a result of the militants' aging from their revolutionary struggle training. As a result, they were obliged to hand over positions of authority to people with university education.
