Personally, I want my establishment Republicans back because I can't stand the Tea Party and MAGA "FU America" Republicans.
I agree... they're going to have to come after Trump to defeat him, and then live with the consequences.
I don't know if, as a party, they are ready to take that measure. They have a huge fear of losing those votes. But in my opinion, they have to stand up to TFG.
Taken from a different POV: I am pretty certain that the Republicans know that if Trump gains the nomination, they lose the election, and maybe additional seats in the Senate or House...
So...
WHAT measures will they be willing to take to get someone else the nomination.? How far will they go? Because they know that they HAVE to have a different nominee, but how do you do that without losing either the MAGA vote, or Trump going off on a 3rd Party bender, which will destroy Republican chances and other offices (not just President) if he does that.
They're in a tricky spot, right now, to say the least. But I'm glad... and they need to get through this "reformation" before I ever take them seriously again...
