As we showed in our analysis of the Clinton/Obama primary fight in 2008, in our book, as well as in analysis of election data from 2010 and 2012, what distinguishes Democratic from Republican voters among whites isn't education level or income level. It's authoritarianism. The data are consistent in this – low authoritarian white folks with less than a college education, or who earn less than the median income, overwhelmingly support Democrats. Conversely, whites with high incomes and high education levels but who also score high in authoritarianism strongly support Republicans. In other words, it's not “working-class whites” per se, who support very conservative candidates. It's authoritarians, whether they are working class or not. This, too, is consistent with the composition of the (not-so-mysterious) Trump coalition.
