The management style of knowing how to pick capable people for a job, and knowing how to delegate responsibilities to those capable people, that management style works everywhere it's tried. Actually, it probably the only style that can work in a job as complex as the US presidency.
Then it's matter patience and having reasonable expectations considering the realities one is dealing with, and having feedback mechanism to assess progress.
This dude has said nothing convincing that supports a notion that Trump could not function in the presidency.
I’m not saying that he could not serve, and probably serve rather well as President. I am saying he is WAY too smart to make a serious run for it.
