Manchin seems to be on board. He'll probably do the Susan Collins routine where he'll furrow his brow, do a little song and dance, and vote with the party.

Parliamentarian: Mr. Manchin
Manchin: This bill is a travesty, it is federal overreach, and a waste of money, and Chuck should be ashamed for putting it up for a vote, we'd be better off just putting all the money in a pile and burning it.
Parliamentarian: Senator, your vote?
Manching: Yea.

Now it's up to Sinema to hopefully not fuck it up.
