title: Carlos Menem
context: Military rule ended in 1983, and the radical Raúl Alfonsín was elected president. Menem ran for governor again, and was elected by a clear margin. The province benefited from tax regulations established by the military, which allowed increased industrial growth. His party got control of the provincial legislature, and he was re-elected in 1987 with 63% of the vote. The PJ was divided in two factions, the conservatives that still supported the political doctrines of Juan and Isabel Perón, and those who proposed a renovation of the party. The internal disputes ceased in 1987. Menem, with his prominent victory in his district, was one of the leading figures of the party, and disputed its leadership.[1]
