Manchin is a snake who will do what is best for Manchin. He only voted to confirm Kavanaugh because it was right before his 2018 election. Once he won that safely, he voted to impeach Trump (twice). The Republicans in WV have run absolute loser RINO challengers to him. Manchin will stay/leave according to which party best benefits him.
I agree. Plus why would Manchin switch? Now, he is the center of attention in every close vote in the Congress. He is the deciding vote.
If he switches, then he is just another RINO like Romney, etc.
