I doubt if either will, possibly Manchin.
You forgot Romney. I'm not sure I would put him in the acquit column until the vote is final.
True.
While Romney is a snake, he is not stupid.
He will seal his political career if he votes to convict.
Even the Mormon Mafia will not be able to save him from that fate.
I was so disappointed in Romney as a candidate but would probably have been even more disappointed in him as president. He is just a phony elitist globalist.
