Over the past few years, a burgeoning literature on Latin American politics has developed, focusing on explanations for the renewed success of the left in the region. Building on electoral trends and public opinion analysis, we argue that the region is experiencing the normalization of democratic politics rather than a backlash or a revolution. Furthermore, we believe that electoral support for the left reflects the disenchantment of voters with underperforming right-wing governments. Using a unique data set covering eighteen countries in the region, our statistical analyses demonstrate that retrospective voting provides a powerful explanation of the recent electoral success of the left in Latin America. Thus, the central implication of our argument is that electoral accountability is still the primary mechanism of controlling the executive in the region's young democracies.
