‘I am getting nervous. But it’s not because Trump is good. It’s because people are stupid’. So said the (usually) very funny US comedian Bill Maher on TV recently. When I heard him say it, my first thought was: Trump’s going to win. Not because Maher is right, but because I recognised something from the EU referendum campaign, when the great and the good – from metropolitan comedians to overpaid columnists — piled in to suggest that Brexit backers were all dimwitted lemmings, marching zombie-like off a cliff. Pro-EU devotees, some from positions of astonishing privilege, were punching down. It wasn’t a good look, and it harmed their cause.
