Del bipartidismo a la fragmentación extrema: la atomización del sistema de partidos en Costa Rica

Abstract

After the 2002 general elections, Costa Rica has moved from a two-party system to an increasingly fragmented one. The erosion of historical loyalties and the dealignment of parties has generated a scenario of partisan fluidity that has been accompanied by a widening gap between parties and society. This paper identifies the main indicators of change, based on a segmented analysis over time: the period of bipolarity (1953-1986), bipartisanship (1986-2002) and multipartyism (2002-present). These indicators, in turn, are brought into discussion with citizens' levels of voter turnout and elites' perceptions of the role of parties. Few differences are observed between the legislators of old and new parties, although we detect that legislators of the newest parties have a more pessimist view regarding integration between parties and society.
