In other words, Clinton, along with Donald Trump, has done for gender what Barack Obama did for race. Obama’s election, UCLA political scientist Michael Tesler has argued, pushed whites who exhibited more racial resentment into the Republican Party and whites who exhibited less into the Democratic Party. Something similar is now happening around gender. But what’s driving the polarization is less gender identity—do you identify as a man or a woman—than gender attitudes: Do you believe that women and men should be more equal. Democrats aren’t becoming the party of women. They’re becoming the party of feminists.

Amidst the current crescendo of sexual-harassment allegations, this is easy to miss. That’s because, in actual cases of sexual harassment, gender identity is obviously crucial. Overwhelmingly, the harassers are men and the victims are women. Gender attitudes—political beliefs about women’s place in society at large—often matter less. Men who support a feminist political agenda, like Clinton supporter Harvey Weinstein, still assault women. Women who oppose a feminist agenda still get assaulted.

But when it comes to the political reaction to sexual harassment, gender identity matters less and gender attitudes matter more. “A sizable minority of American women,” note Huddy and Willmann, “do not believe in the existence of gender discrimination, think that women who charge men with gender discrimination are trouble makers, and are inclined to side with a man accused of discriminatory behavior.” And Hillary Clinton’s presidential candidacy seems to have made these women more staunchly Republican.

Which helps explain why female Republicans express far less support for feminism than even male Democrats. Earlier this month, the research firm PerryUndem found that Democratic men were 25 points more likely than Republican women to say sexism remains a “big” or “somewhat” big problem. According to October polling data sorted for me by the Pew Research Center, Democratic men were 31 points more likely than Republican women to say the “country has not gone far enough on women’s rights.” In both surveys, the gender gap within parties was small: Republican women and Republican men answered roughly the same way as did Democratic women and Democratic men. But the gap between parties—between both Democratic men and women and Republican men and women—was large.

Since Trump’s election and the recent wave of sexual-harassment allegations, this partisan divide appears to have grown. In January, when PerryUndem asked whether “most women interpret innocent remarks as being sexist,” Republican women were 11 points more likely than Democratic men to say yes. When PerryUndem asked the question again this month, the gap had more than doubled to 23 points. A year ago, Democratic men were 30 points more likely than Republican women to strongly agree that “the country would be better off if we had more women in political office.” The gap is now 45 points.
