Selecting for Masculinity: Women’s Under-Representation in the Republican Party

Abstract

The gap between women’s representation in the Democratic and Republican parties has grown significantly in the last three decades. We argue existing explanations undervalue voters’ contributions to this trend by focusing on voter responses to candidate sex rather than candidate gender. We theorize that Republican voters (especially the most conservative) prefer masculine candidates in intraparty and entry-level elections. Because sex and gender are correlated, this limits the number of Republican women who advance through the political pipeline. Experimental vignettes from two rounds of the Cooperative Congressional Election Study (N = 2,000) and two large surveys of Republicans (N > 10,000) show that Republican (but not Democratic) voters penalize candidates with “feminine” self-presentation regardless of the candidate’s sex. Original data on the self-presentation of Republican candidates for entry-level office (N = 459) confirm Republican candidates often present themselves in gender-stereotypical ways. In short, voters play an underappreciated role in the partisan gap in women’s representation.
