We cannot ignore the fact that the populist sensation of this election hasn’t been Bernie Sanders. It’s been a racist, nationalist demagogue-for-hire with no sincere ideology beyond his own vanity. Mr. Trump is a cipher; his voters love him because he does nothing but hold up a mirror to their basest prejudices and bask in the feedback loop of narcissism. They’re not “afraid”; they’re leading Mr. Trump as much as following him. They called him into being, not the other way around.
