Voter support for women candidates in American politics may best be summed up by the often-repeated phrase, “when women run, women win.” This statement indicates that when compared to male candidates running in a similar capacity, such as candidates for open seats in which no incumbent is present, female candidates are equally likely to win elected office. Voters, therefore, seem equally likely at face value to support female candidates. However, the literature on voter support for women candidates suggests that this voter support may be more conditional in nature. A central research thread on voters and women candidates is how voters perceive women candidates and, in turn, their electability. Research on gender stereotypes and candidates examines voter perceptions of the traits they typically associate with men and women, candidates, and officeholders and the circumstances under which these traits make gender and political candidacy more or less attractive. The literature on political party and voter support for women candidates explores how gender and party affect levels of voter support and is offered as one explanation for the party imbalance in women’s representation with female Democrats significantly outnumbering female Republicans as candidates and officeholders. Researchers have also examined how voters evaluate other components of women’s candidacies, including their party affiliation, race, ethnicity, and sexual orientation. In addition to personal characteristics, scholars have explored how the type or level of office impacts voter support of women candidates with certain types of elected positions often considered more or less well suited for women candidates. More recently, a thread of research on voter support for women candidates has focused on women’s absence from the nation’s highest elected position—the US presidency. Scholars, and the candidate herself, have assessed voter support for or opposition to Hillary Clinton’s unsuccessful presidential bids in 2008 and 2016. This line of research includes public opinion polling that measures both the abstract idea of electing a woman president as well as electing a specific woman president, namely Clinton.
