The association between how citizens perceive economic performance, insecurity, or corruption and how they evaluate the president varies systematically across Latin American countries and within them over time. In particular, while presidential popularity reflects these outcomes in the average Latin American country, survey data from 2006–17 confirm that the connection between government performance and presidential approval is generally stronger when unfragmented party systems or single-party majority governments make assessments of political responsibility easier. While these results suggest that the region’s citizens do not blindly blame the president for outcomes where political responsibility should be shared, they also remind us that there are many countries in the region where fragmented party systems weaken the conditions for effective political accountability.
