Elections involving women candidates in the United States can offer unsettling examples of voter gender stereotypes, but research on women candidates provides little in the way of available data that allow us to link stereotypes to voter decision-making. This project reports results from a 2010 survey designed to examine gender stereotypes, candidate evaluations, and voting behavior in U.S. House elections with women candidates running against men. In general, stereotypes are not a central part of candidate evaluations or voting decisions, but the political party of the woman candidate can shape their role in candidate evaluations and vote choice.
