I hope that when the dam breaks it washes away the entire GOP

If you look at the Labour Party in the UK, they walked in with comically oversized majorities last year. Then they proceeded to govern exactly like their Conservative predecessors - with no few MPs gleaned from the ranks of fleeing conservatives - such that Reform UK is now ready to pick up the Prime Ministership in the next election cycle.

The problem with the modern American conservative movement is that its not confined to the GOP. It is a consequence of the donor base. And the donors continue to be enthusiastically bipartisan.
