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.
Oh, and this: no matter how ideologically “pure” or “impure,” there are people who want to WIN. They want to be associated with winners. We will see a LOT of GOP regulars who don’t particularly like Trump (just as happened with Reagan) latch on because they want to win, and I’m not just talking about committee chairmanships and stuff, but just the aura of being a winner. That still hasn’t died in America.
