The present study used nationally representative American National Election Studies (ANES) data to examine the potential role of sexism in the 2016 presidential election. We hypothesized not only that sexism would predict voting for Trump (vs. Clinton), but that its role would be stronger on the political left (vs. right). The sample consisted of 1916 Clinton or Trump voters (51.41% women; Mage = 51.78, SD = 17.16; 79.5% White) who completed measures of political ideology and hostile sexism. Greater conservatism or sexism significantly predicted voting for Trump (vs. Clinton). As expected, sexism was a significantly stronger predictor of voting for Trump the more left-leaning (vs. right-leaning) the voter. Not only was Clinton correct that sexism played a role in her electoral loss, but she correctly characterized sexism as endemic, an influence especially perceptible on the left.
