Some liberal think tank put out their list of PINOs (Progressive In Name Only). They want them primaried and replaced with more progressive candidates. My Rep happens to be one of the 6 on the list.
It’s literally becoming Progressives vs Trumpists and those of us in the left or right center can either pick one or get out of the way. Progressives are now openly treating people like Joe Manchin the way Trumpers treat people like Mitt Romney. Both sides want to purge themselves of anything moderate in their ranks.
