Trump will learn from this. What he will learn is that the media flak made him fire a capable man who didn’t know how to play the Washington game.
What he should learn is that yet again he hired an utterly incapable, seemingly deranged neophyte who should have been nowhere near the wheels of power. But he seems incapable of learning from his mistakes. Either he will continue to spiral down in flames or gradually grown ups will survive the winnowing and he will lose power within his own administration, they will effectively route around him and he will become Reagan 2, a figurehead.
I honestly thought the Republicans would have found a way to do this already, having so much experience with imbecile leaders, and I didn’t find it a comforting thought.
