But you're absolutely right about who he fires. What he'd have to be most concerned about is keeping people who would be sabotaging him.
You'll appreciate this. Was talking with a former GOP county head---big, important OH county---and he was supporting Kasich with all the usual complaints about Trump. Ultimately he said, "Well, Kasich is the only guy where I would have a job in the administration." Bingo.
One of the benefits of a Trump is that he has the money to do a lot of the things that normally the RNC would do in the election. But there still are a lot of nuts and bolts to take care of that don't involve money. Experience and knowing who to talk to are important at the local level. I hope the Tea Party energy and grassroots can overcome RNC sabotage.
