The Center for American Women and Politics (CAWP) is tracking gender differences in support for the major-party candidates in the 2020 presidential election at the national level and in battleground states. We are tracking both the gender gap in likely vote choice between men and women voters for the leading candidate and the reported difference in support for each major party candidate among women voters. For historical context, see CAWP's research and data on gender differences in voter turnout and the gender gap in vote choice, partisan identification, and policy attitudes.
