NOPE!!! If the GOPE or the RINO base want to kick Team Trump out, that’s one thing...but Team Trump is staying where they are and fighting this one out...Trump doesn’t walk away from a fight, and they don’t know just how many supporters Team Trump has...
Neither does he ignore a deal he's made. Part of that deal was that Trump be treated fairly by the RNC. Some party spokepeople have been way out of hand, and the RNC doesn't seem to be stopping it.
If Trump goes third party and does it right, with an excellent VP choice and a viable campaign in every state, I suspect he can win. If establishment 'pubs keep demeaning him, he can't win as a Republican but he can win as an independent.
JMHO
