Here is one way he can deal with recalcitrant senators.
Since Trump owes no one he will hire the best in the business at counseling him and congressional liason. The latter will act as the carrot. The former, like Gingrich, will know where the bodies are buried, where each senator derives his power and his campaign money. If the carrot doesn't work, Trump goes to the stick. When you separate the senator from his voter base and his contributors you cut him off. The same technique will be used to woo enough dem senators to side with Trump on certain issues.
If I can figure this out I'm sure a billionaire who doesn't smoke or drink or sleep and is a freaking genius can figure it out.
Yes, I agree there are ways to deal with these obstructionists. Reagan got past a Dem House & DJT didn’t get where he is by being stupid or timid,
