Barbara Burrell presents a comprehensive examination of women’s candidacy for the U.S. House of Representatives in congressional elections from 1994 through 2012. Analyzing extensive original data sets on all major party candidates for 10 elections—covering candidate status, sex, party affiliation, fundraising, candidate background variables, votes obtained, and success rates for both primary and general elections—Burrell finds no evidence of categorical gender discrimination against women candidates. They compete equally with men and often outpace them in raising money, gaining interest group and political party support, and winning elections; indeed, more women hold seats in the House than ever before. However, Burrell concludes, women have not advanced more quickly because newcomers face difficulties in challenging more experienced candidates and because women are not taking advantage of opportunities to run for office.
