Short- and Long-Term Partisanship: Campaign Effects and the Stability of Party Identification in Latin America

Abstract

This study focuses on a dimension of partisanship overlooked by most comparative studies on campaign effects: individual-level stability, a measure of short-term partisanship. Some voters in young democracies are able to develop partisanship as a screen through which they observe the political world, leading them to interpret new information in a manner that reinforces their political predispositions. However, some voters lack long-term partisan attachments, enabling them to update their party identification as the campaign unfolds. These voters have a harder time reinforcing their precampaign dispositions and are more likely to change their vote intention. The findings suggest that for some voters, partisanship and vote choice are empirically intertwined.
