Partidos politicos, elecciones y lealtades partidarias en Costa Rica: Erosion y cambio

摘要

Fernando Sanchez's careful, well-researched work presents a systematic examination of the process of political dealignment in Latin America through a detailed case study of Costa Rica's changing party system. This relatively common phenomenon of declining partisan attachment to political parties has been examined and well addressed in the political science literature for advanced western democratic countries. The author builds on these existing theories to present a persuasive, theoretically sophisticated explanation for the decline of partisan support for Costa Rica's oldest political party, the Partido Liberacion Nacional (PLN), and simultaneously offer insights into dealignment processes in other Latin American countries.
