A whole array of studies has shown that the physical appearance of candidates running for elective office matters. However, it is unclear whether attractiveness or perceived competence is the source of such electoral advantage. In addition, the gender of candidates might interact with perceptions of physical appearance. With the help of Canadian student coders and through the use of a web-based survey, we measure the threefold link between physical attractiveness, perceived competence, and gender for all races in the 2008 U.S. House of Representatives elections. We find that both the attractiveness and perceived competence of candidates matter for candidates’ electoral successes; the former having an important effect in intra-gender races and the latter in inter-gender races.
