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.
Workers' Revolutionary Party (Mexico)
From their base in the 1968 student movement, the PRT grew quickly, soon gaining bases of support among some telephone, electrical, nuclear, and hospital workers. By the 1980s, it was the largest far-left party to challenge the ruling Institutional Revolutionary Party (PRI). In 1981, the federal government recognized the PRT as an official nationwide party. In the 1982 general elections, it was also the first Mexican party to raise gay rights as a campaign issue; the party fielded several openly gay candidates for the Chamber of Deputies. It also entered informal alliances with the other main party on the far left, the United Socialist Party of Mexico (PSUM).
