We document that Latin American countries are characterized by personalist leaderships (e.g., Fujimori in Peru, Uribe in Colombia) and important historical cleavages (e.g., anti vs. pro-PLN in Costa Rica) that blur class-based vot- ing patterns and have led in some cases to the emergence of competing pro-poor and ethnic-based competing coalitions (e.g., PRN-PLN in Costa Rica, Fujimori-Humala in Peru) over the last decades. The party systems of Costa Rica, Colombia and Peru have thus generated volatile political socio-economic cleavages, while in the more institu- tionalized party systems of Argentina, Brazil, Chile and Mexico they have been less volatile. *Oscar Barrera (World Inequality Lab):
