Trump’s other gift — the one that gets less attention but is perhaps more important — is his complete lack of shame. It’s easy to underestimate how important shame is in American politics. But shame is our most powerful restraint on politicians who would find success through demagoguery. Most people feel shame when they’re exposed as liars, when they’re seen as uninformed, when their behavior is thought cruel, when respected figures in their party condemn their actions, when experts dismiss their proposals, when they are mocked and booed and protested.

Trump doesn’t. He has the reality television star’s ability to operate entirely without shame, and that permits him to operate entirely without restraint. It is the single scariest facet of his personality. It is the one that allows him to go where others won’t, to say what others can’t, to do what others wouldn’t.
