If the GOP even tries to do what you're implying, it will mean the end of the party. I don't believe kamikaze is their style which is why I believe he met with the party elites yesterday.
The message should be clear. If Trump is going to be the guy, he needs to start acting more presidential and work to unite the party rather than engaging in 7th grade schoolyard nonsense.
He also needs to get better people working for him because he's being outplayed on the ground. That's because he's not spending money. You cannot save your way to prosperity in a national election.
You can be reactive or proactive. I prefer he be the latter, especially if he's going to take on the Clinton/DNC machine. He has no idea what is coming at him. At some point, he needs a wake up call. Let's hope this is it.
As for the end of the party,. then they should have thought about that when they got cruz and Kasich to do their dirty work.
the party is dead to me and many others.
