Newt Gingrich said something in the paper in morning about Trump being a good learner. Others, including Gail Collins in the Times today, say he's very curious in small meetings and asks a lot of questions. So here's a hypothesis: Trump gets good reviews from acting Presidential Tuesday night. That represents the "swamp" (aka the established political order) rewarding him for conforming to its norms. If Trump truly does learn, which is to be proven, and he truly does crave praise, which seems well proven, then he will gradually alter his behavior so he's more like a conventional president. So what we're seeing now is a process where the establishment is punishing and rewarding Trump for his behavior.
I think the hypothesis is reasonable. However how likely to change is a 70-year old man? Not very, I'd say. On the other hand, he doesn't have a long history as a political actor, so maybe more likely than Nixon, who tried to change every few years. There's also incentives to stay the course, maintaining faith with his supporters, and close associates.
Conceivably if the hypothesis works, and Trump is lucky with the economy and foreign policy he'll have a successful presidency.
