When does a Party System Change? An Electoral Analysis Perspective from the Colombian Case

Abstract

This article looks at the change in the Colombian party system, using an electoral analysis perspective. Using a principal component analysis, it identifies the territorial structures in the electoral behaviour of the country for the Senate elections over the past two decades. Results show that the 2003 political reform encouraged the reorganization of the party system among the traditional liberal/conservative cleavage, now expressed by a multi-party system. The 2014 elections suggest a deeper change.
