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.
Institutional Republican Party
It was created in 1989 by former president and dictator Efraín Ríos Montt, and formally registered in 1990. It chose Ríos Montt as its candidate, but he was not allowed to stand because of a constitutional ban on former coup leaders such as himself from seeking the presidency. By the time the decision was made to ban him, it was too late for the FRG to choose another candidate. They did win 10 seats in the National Congress in those concurrent elections. It was the main component of the "No Sell-Out Platform," an alliance of right-wing parties.
