As for Trump being a less decisive executive; I've never had any expectations as I've always believed that running a corporation is far different than running the government.
No question, because you really only have control of the people in your branch. Here's my biggest problem with the man - I just don't believe what he says. What got him elected was the frustration with establishment politics. It was obvious he was opposed by leadership during the campaign. The lay of the land was apparent, once they balked on a clean repeal/replace of O-care.
Right then and there, he should have had his people forming exploratory committees to find candidates, fundraise, and clean house in places where it would really matter. He won Wisconsin, so find someone other than that joke candidate Nehlen to primary Ryan. Trump is supposed to be a negotiator. The best leverage he could have is seriously threatening careers.
I just don't find him to be genuinely interested in doing what it takes to get that accomplished. If he was, people like Gorka and Bannon would still be around.
