Ideology, political sophistication and vote in Brazil

Abstract The spatial theory of voting assumes that voters will cast their votes for the candidate whose policy position is closest to their own views. The goal of this paper is twofold: the first one is to test this assumption for the Brazilian presidential elections from 2002 to 2014. In order to do that we use data from the Brazilian Electoral Study along with scaling methods. The results suggest that the probability of a voter casting her vote for the candidate whose policy position is closest to her own is pretty high. The second goal of this paper is to assess if this result holds despite voters’ political sophistication. In other words, we test if ill-informed voters make their electoral decisions based on non-spatial candidate characteristics. The results contradict this idea. Politically ill-informed voters also choose the candidates whose views are closer to their own.
