Multiparty politics in Argentina? Electoral rules and changing patterns

This article attempts to illuminate some institutional features of the past and the current electoral systems of Argentina and the problematic relationship between these characteristics and the trend of changes that the party system has been experiencing since the return of democracy in 1983. The focus is on the dangers of political stalemate that might have developed if the institutional arrangements implemented at the end of the military rule had not been reformed subsequently. The study has two objectives: (a) to demonstrate that there is a trend towards an increasing fractionalization of the Argentine party system; and (b) to show that the combination of an electoral college with a majority requirement, proportional representation to allocate presidential electors, malapportionment among districts, and this increasing process of pluralization in most provinces (where presidential elections were decided because of electoral college complexities) threatened the stability of democracy.
