The Electoral Success of the Left in Latin America: Is There Any Room for Spatial Models of Voting?

Abstract

Why have moderate electorates elected and reelected leftist governments in Latin America over the last twenty years? Scholars who rely on the classic Downsian logic of the median voter theorem have observed a process of ideological moderation among the most salient left-wing parties in the region. However, there have been no systematic attempts to evaluate the moderation thesis at the comparative level, either across Latin America or within cases over time. This article uses a directional model in the spatial modeling tradition to argue that the success of the left rests on the provision of clear leftist programmatic cues to voters. Data coming from the Comparative Study of Electoral Systems for five Latin American countries during 1994 and 2014 show that left-wing parties won on left-wing platforms across the region, while an in-depth study on Brazilian elections reveals that leftist voters of the Workers’ Party in 2002 were driven by programmatic cues that largely disappeared during the 2010 elections.
