It seems silly to say that Trump is remaking his cabinet in his own image; after all, he appointed the original one. That said, it is obvious that he didn’t really expect to win the election, and had no plan for what would happen next, so his original cast of advisers to some extent reflected the recommendations of others. Now, after a year in office, he thinks he knows how to do the job, and he wants to get rid of his minders.
The new cast of characters will have the following characteristics: good on TV; fun to be around; and completely loyal. Intelligence and competence will be unnecessary; after all, we have his infinite wisdom to rely on.
The Senate obviously has a role to play in this. Will GOP senators insist that Trump appoint qualified people? Don’t bet on it.
