Donald Trump in 2016 elicited eye-rolls from K Street Republicans and chuckles from self-satisfied liberals when he promised to make the Republican Party a working-class party. Then Trump went ahead and won Michigan, Wisconsin, Ohio, and Pennsylvania, largely by over-performing among union households.

Almost overnight, the Left’s stereotype of a Republican swung from detached country-club elite to dumb uneducated brute. Two years later, Democrats took over the House of Representatives, in part, on the strength of that country-club vote — the upper-middle-class white suburbs that had loved Mitt Romney but disliked Trump.
