If it's just one vote, it's really not hard for some orgs to collaborate on bullying the shit out of him to make him capitulate. What happened to all those kayakers screaming at him on his yacht, or the people chasing him at the marina? That should 10x bigger, and 24/7.

Of course as I'm writing this I'm remembering he's the face of internal opposition and there's probably 10-15 other Dems who don't want it either.
