If the Democrats need his vote, they got it. If they can flip a few more Republicans, which should be as difficult as breaking an eggshell, they may let him slide. But, in the end, always look for a Democrat to behave as a Democrat. Unfortunately for us, the same holds for Republicans also.
Even if the Dims get cloture, the Repubs can slow this down voting for amendment after amendment to lard it down. The bill goes to the joint house meeting where the two houses again have to agree to pass the same bill. Time is not on the rats side. Tick toc tick toc.... Dems - oh damn - time’s up, it is January.
