Well, I'd prefer you do it, since you raised the question. Google "RNC's bad treatment of Trump" and pick out something to read from the 2.79 million hits. Better still, despite his lead in the polls, show me where the RNC is supporting the front-runner.
Trump does not so far have specific objections to his treatment by the RNC in regard to debates and primaries, does he?
The RNC needs to go, probably to the last member. But Trump does demonstrate that they cower when faced with a serious threat, such as from Trump himself, or from Democrats.
