Institutional Revolutionary Party
Cárdenas's successor Manuel Ávila Camacho gave the party its present name in 1946. The party, under its three different names, held every political position until 1946 when the PAN started winning posts for municipal president and federal deputies and senators, starting in 1946, after the party changed its name to its current name, the Institutional Revolutionary Party. By then, the party had acquired a reputation for corruption, and while this was admitted (to a degree) by some of its affiliates, its supporters maintained that the role of the party was crucial in the modernization and stabilization of Mexico.
Lázaro Cárdenas
The party that Cárdenas founded, the Partido Revolucionario Mexicano (PRM), established the basic structure of sectoral representation of important groups, a structure retained by its successor in 1946, the PRI. The PRI continued in power until 2000. This is attributed by some to electoral fraud and coercion. This legacy led his son, Cuauhtémoc Cárdenas, to form the Democratic Revolution Party (PRD) to contest the 1988 presidential election. Since that year, the PRD has become one of the three major parties in Mexico, gaining working class support that was previously enjoyed by the PRI.
