For the next two years he can be very useful though.
Capito has been a space filler.
Not if we lose Georgia. Then Manchin does us no good.
If we win Georgia, then convince Manchin to switch parties by offering him support in 2024 (but not beyond).
I doubt it.
He could have been useful if he had switched parties two years ago and given Republicans control of the Senate. In exchange, he could probably have cut a deal with McConnell to support his re-election in the Republican primary in 2024. He would have been a left-wing liberal RINO, but McConnell seems to like those.
Now he has nothing to offer and nothing to gain. He is likely to be primaried out by the democrats in 2024, because they all hate him now. If he manages to make it through the primary he will lose in the general election, because the 60% of West Virginia voters who voted for Trump in 2020 also hate him now.
He won't even be able to get a talking head job on CNN, MSNBC, ABC, CBS, NBC, etc., because the media all hate him now.
Useful idiot so to speak.
