McCarthy deserved to be ignored. He was pro-election-theft and pro-insurrection.
In the end, McConnell isn't Moscow Mitch. He's an untrustworthy arsehole, but an untrustworthy American arsehole who chose the right path in the end. Maybe he'll finally see what a disaster his tactics have been for the country and his own party. Who knows? But there is a line he wouldn't cross.
I imagine he'll find a way to remove McCarthy.
