“White college-educated voters are becoming more Democratic as white non-college-educated voters are becoming more Republican. That’s because of the fundamental political change Ruffini says is the underlying issue for all of these shifts. Education is becoming the great divider in American politics, helping to explain Democratic improvements with well-educated white voters and their weaknesses with non-college-educated white voters — and now non-college-educated voters of color too. While class and income used to be better tools for telling differences between the political parties’ coalitions, “[t]oday, how much money you make no longer dictates how you vote,” he writes early on. “A college diploma has replaced income as the new marker of social class and the key dividing line in elections.””
