He wasn't serving up these insults for effect--well, not entirely. And his behavior wasn't carefully calculated; it was tit for tat, and he likely would have said what he'd said even if no one was left standing with him. (This very lack of calculation, this inability to be political, was part of his political charm.) It was just his good luck that the Trumpian 35 percent--that standing percentage of people who, according to most polls, seemed to support him no matter what (who would, in his estimation, let him get away with shooting someone on Fifth Avenue)--was largely unfazed and maybe even buoyed by every new expression of Trumpness.
