UNIONTOWN, Pennsylvania — Paul is a 60-year-old, white, working-class guy eating chicken and biscuits smothered in gravy at Mark C’s diner on the edge of town.

Paul isn’t very political — he doesn’t have strong views on public policy. “I’m not into this Republican or Democrat thing,” he says. In fact, Paul never voted until he was in his 50s — until 2016. “That was the reason why I even registered to vote, so that I could vote and vote for him.”
