How partisan affect shapes citizens' perception of the political world

Abstract

We explore how partisan affect shapes citizens' views of party ideology and political competition. We argue that voters' affective ties to parties (both positive and negative) lead them to perceive the ideological positions of those parties as more extreme. Further, when voters are "affectively polarized," i.e., they strongly like some parties and dislike others, they are more likely to view politics as high stakes competition, where ideological polarization is rampant, participation is crucial, and electoral outcomes are highly consequential. Using cross-national survey data covering 43 elections in 34 countries, we show that partisan affect indeed impacts perceptions of party ideology and that affective polarization alters beliefs about the nature of political competition.
