Just an impression of mine, in hindsight, but:

—Trump was playing with house money. Was willing to do, say anything. Didn’t really care about winning. Wanted to win. But wanted to do it his way. Didn’t have anything to lose.

—Hillary was afraid to lose (this is where the email stuff and the DNC hack and everything else probably hurt her). Rarely let loose. Played by old rules of what was OK to say, how it was OK to act. We’re only a few years removed from the Dean Scream, George Allen’s Maccaca moment, Romney’s 47% and other singular gaffs that have doomed other campaigns. Those rules suddenly don’t apply anymore.
