Votos y estratos: la creciente estratificación social del sistema partidario colombiano en el siglo XXI

Since the end of the twentieth century, the weakening of the traditional class cleavage in the electoral behavior of Western democracies has become evident; however, studies are scarc-er for third-wave democracies. Colombia is an interesting case as it shows signs of a consoli-dating partisan system since the political reform of 2003. Based on an analysis of the vote by so-cio-economicstratum in the five largest cities in the last four legislative elections, we find that this country shows, contrary to international trends, a tendency towards greater social seg-mentation of the vote, and we propose some interpretations in this regard.
