And Trump's supporters are all members of that organization and we have been winning by the rules of that organization.
The leadership has been working outside of the rules to attack their own front runner, instead of letting the primary process work as it is intended.
AND openly plotting ways to game the rules to subvert the process.
Expect a move to repeal Rule 40, with requires in the event of a brokered convention that the candidate to be picked has to have won 8 states.
That is changing the rules in the middle of the game.
You have not won 1237 delegates. If Trump wins that, he should be the nominee. If he doesn't, then he should not. And he probably won't.
This system, or a variation of it, dates back to the 1830s. It is older than the Republican Party itself.
It shouldn't be changed simply because a candidate who didn't win the required delegates or a majority of the voters, and didn't know the process, thinks he should be the candidate.
Trump didn't even know some of the most basic facts of this system. That he didn't would astonish most people. Except, of course, Trump supporters, who seem immune to astonishment.
