Movimiento al Socialismo (Argentina)
The Movimiento al Socialismo ( MAS ; más means “more” in Spanish ) in Argentina is a group with Trotskyist roots. It was founded in 1982 by Nahuel Moreno as the successor to the Partido Socialista de los Trabajadores (PST) and led by Moreno until his death in 1987.
In 1989 the MAS achieved more than 400,000 votes in the presidential elections and a seat in the Chamber of Deputies in the parliamentary elections in the same year through the Izquierda Unida (IU) electoral alliance ; Nevertheless, after Moreno's death in 1987, the group experienced internal wing fighting, in the course of which several political organizations split off. At the moment the MAS is politically insignificant.
