EVERY SINGLE ONE of them should be voted out of office the next election cycle,REGARDLESS of who they are running against. I am tired of hearing "Yeah,but.....,if we don't vote for them someone further to the left will take that seat!" So what? It's already held by the left. Get those posers out of there so actual conservatives can run against whatever baboon the DNC installed in those seats.
They won't be though. McConnell has a stranglehold on the Senate the way Pelosi does on the House.
Any threat by a real Conservative to one of the inner circle disciples of McConnell gets met with threats to ad agencies and PR firms of being blacklisted from any business from the GOP in the future. NRSC money goes to those that are deemed worthy by Turtle. And if Mitch feels threatened by your arrival in D.C....if your race is close with a Progressive in your state...Mitch will ensure you don't get funds to ensure your campaign is the victorious one.
Pelosi runs the House the same way...hence all those new Progressives (except for one) that said they'd vote against Pelosi if elected suddenly fell in line.
The only way the old bulls are gonna leave DC is if they go feet first.
