Research shows that areas with high levels of aggregate religiosity are less likely to elect female candidates to national, state, and local offices. These studies, however, do not determine the causal mechanisms underlying this relationship. In the present analysis, we seek to examine what role, if any, religious exposure and tradition play in determining individuals’ general election vote choices in mixed-gender contests. To explore this relationship, we use data from the 2010 and 2012 Cooperative Congressional Election Studies. We find some evidence of a relationship between religious beliefs and voting for female congressional candidates; when compared to secular voters, evangelical Protestants and Catholics are more likely to vote for Republican women and less likely to support Democratic women. Our results, however, also underscore partisan identities’ central role in shaping individual vote choice, regardless of a candidate's gender.
