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.
Bloc party (politics)
In Mexico during the rule of the Institutional Revolutionary Party (PRI, 1929–2000), partidos paleros (satellite parties) included the Authentic Party of the Mexican Revolution and the Socialist Popular Party. These helped the PRI government give the superficial appearance of a competitive democratic system. In fact, both satellite parties fully supported the government and co-nominated the PRI candidates for the Presidency of Mexico until 1988.
