I only mentioned Romney because he's the only one who came quickly to mind. I did add "and his ilk". There are quite a few GOP Senators who have been less than enthusiastic about Trump's brand of politics and would like to put him in the rear view mirror. There are lots of others who are loyalists. It will be interesting to see who wins out in the end.
The "establishment" of the GOP has alienated more than half of their constituents. As they continue their death march, they are not garnering any new supporters. Conversely, the new DCP has gone so far into fascism/socialism that the party moderates are also bailing on them. Expect Xiden to polish them off, and also expect to see His Fraudulancy usher in republican control of the House and Senate in 2022.
In the free states we should expect to see more R seats gained and the establishment R's primaried out. The blue shit hole states have roughly 18 months to try to clean up their voting systems before they go to a one party state like California.
Xiden is making the most compelling argument of why to never let DCP members have power again. One week in and he's already creating one disaster after another.
