This paper analyzes the persistence of bipartidism in Valle del Cauca (Colombia), from the results of the local council elections in the 42 districts of the department, between 1992 and 2015. In order to explain this electoral phenomenon, a classic institutional variable such as the magnitude of the district (MD) is used.Using panel data on a random effects model, this paper seeks to assess the existence of a causal relation between MD and the fragmentation of the party system. Then, it shows in which districts, of specific magnitude, the persistence was stronger. In other words, in which districts the transition process to a multiparty system takes longer and what are the key moments during this process.To analyze the persistence of bipartidism the segmented Nagayama Triangle (Nagayama, 1997; Grofman, Chiaramonte, D’Alimonte & Feld, 2004) is used, which reveals information about t...
