Posting here, I am a broken record, but I will repeat:
Donald Trump will never forgive a relatively modest number of elected Republicans; and he will co-opt and rehabilitate most others. Reconciliation will come for Pence, Haley, Rubio, and various others.
Liz Cheney and Mitt Romney are toast. There will be a banding together of the GOPe, and so the outcomes for Susan Collins and others are yet to be determined. I think Trump will give them a long rope ... extending for six months or more ... but they need to cut Cheney, Romney, Jeb Bush and others loose and let them sink. Otherwise, they will go down as well. There is a line and the Susan Collins and Mitch McConnels need to decide which side of the line they’re on. Mitch has clearly been on the wrong side of the line, but he is a crafty and wise fellow and he has time and power enough to move. His fate is not yet sealed.
Trump needs to attack their funding. No one should donate to the Repukes and Trump should be leading that charge.
