Rothwell also suggested the reason might have something to do with parents and children. Trump voters tend to be older, blue-collar workers, and recent generations have had more difficulty getting well-paying jobs that didn't require much education. Those opportunities have largely dried up. And now, Trump supporters tend to live in places where the world has gotten visibly tougher for the kids on the block. It's easier to agree with Trump's narrative about American decline when you have seen your own child fall down the economic ladder.
