This is so frustrating to watch. I'm not a Trump supporter by any means but what's happening is deeply unfair. To those who say "it's part of the game", do you remember Romney or McCain or W having to go back to elections they had already won and re-fight them, not to win votes, but to outmanouver local party activists abusing the rulebook to put up delegates who support the guy who lost instead of the guy who won? It's insane that this can happen.
Yes. I distinctly remember Ron Paul dominating these kinds of events, and there being a real fear that if Romney and Santorum deadlocked the nomination would ultimately go to Paul (who had way less popular support than Cruz, btw). The whole thing ended up moot because Romney won a majority of delegates.
To summarize, it's always been part of the process, but
trumpies haven't always been part of the process and now they're butthurt having found out about it.
