That paragraph, politically lethal if I were writing about someone else, encapsulates precisely why Trump is so hard to stop. He is, among other things, scandal-proof. At the moment, an army of journalists is scouring the land looking for whatever Trump has done that we might not yet know about. Trouble is, there is little that can be revealed. Call him a womanizer, and he shrugs. Say he lies, and he lies by saying he doesn't. Confront him with the truth and, as he did by insisting on Muslim revelry in New Jersey following the Sept. 11 attacks, and he just perseveres. He cannot be shamed.
