No, the nominee IS NOT going to have to make peace with them.
Please explain that reasoning.
This is situation where the GOPe is going to have to tolerate the nominee the voting public chooses.
The nominee goes on to the election. The GOPe tags along saying yes sir no sir.
The reason is simply that they’re called ‘the establishment’ for a reason.
The nominee will need their support- to ‘some’ extent- to bring along the Party members who did not want that nominee. “A house divided” and so forth. They can cause tremendous fifth column problems. Many donors may defect to the other side- the opposition needs to be denied that funding.
Lots of reasons.
The GOPe has adamantly insisted on their own way so far.
Is this what happened with Reagan? If so; they GOPe still won. They managed to foist GHWB on him as his VP. If memory serves; GHWB went on to squander the legacy given to him by Reagan.
