The great problem with Trump, predictively, is that he’s fickle. He often doesn’t do what he says he’ll do. Even if he was sincere he’s easily handled by flatterers. The best model for Trump is an arrogant and touchy king who wants to be made to feel he’s amazing.
This means that court games matter even more than in a normal Presidency, and those who play them best have the most power and influence.
But even a good courtier can step wrong with Trump and be pushed out. The limelight has to stay on Trump himself. A courtier can have great power, but the credit and the media must flow to the top. The last thing any courtier wants is to have people saying publicly that they’re the power behind the throne.
