Trump is following his playbook "The Art of the deal." He thinks that he can use those TRICKS even as President of the U.S. It's called "resistance fatigue", and it also ties in with how he starts his negotiations. He doesn't begin with a "fair for you fair for me" deal, he goes as outrageous as possible and lets the opposition talk it's way down a little bit to come to an agreement that still benefits him. See Mexico. Also applies to the protests which I mean, it's a bit tough to protest EVERYTHING at once when it's all coming in at once. For example, with religious contributions to political organizations, people may be like, "this is bad, but we reallly need to focus our attention on immigration and planned parenthood." It's a whole blitzkrieg of bullshit that people have to fight, and the idea is that they can't win 'em all. He's coming at it from the authoritarian businessman's angle, with little regard for the Constitution or design of the American political system. Anything he sees a way of doing, whether or not there are questions to its legality, he's going to pounce on. People need to stop looking at this like a liberal or a republican and start looking at it like an American.
