Abstract

The Primary, Open, Simultaneous and Compulsory Elections Law (PASO in Spanish) was passed in 2009 in Argentina by the national Congress. Later, eleven provinces enacted their own PASO laws. Buenos Aires Province was the first. In this paper we analyze the effects of Law No. 14.086 on Buenos Aires’s party system. We focus on the main objectives of the law and we have assessed its accomplishment. We study the competition for legislative and executive posts in the general elections held between 1983 and 2019 and primary elections between 2011 and 2019. We conclude that in primary elections only a minority of political parties compete with more than one list, nevertheless, the PASO Law curtailed party competition reducing the electoral fragmentation and increasing the votes won by the main parties. All in all, we show that the competition in primaries with more than one list does not affect the results in the general election.
