Abstract

We argue that the factors shaping the impact of partisanship on vote choice—“partisan voting”—depend on the nature of party identification. Because party identification is partly based on images of the social group characteristics of the parties, the social profiles of political candidates should affect levels of partisan voting. A candidate's religious affiliation enables a test of this hypothesis. Using survey experiments which vary a hypothetical candidate's religious affiliation, we find strong evidence that candidates’ religions can affect partisan voting. Identifying a candidate as an evangelical (a group viewed as Republican) increases Republican support for, and Democratic opposition to, the candidate, while identifying the candidate as a Catholic (a group lacking a clear partisan profile) has no bearing on partisan voting. Importantly, the conditional effect of candidate religion on partisan voting requires the group to have a salient partisan image and holds with controls for respondents’ own religious affiliations and ideologies.
