Will it get them the votes? I don't think so but the repubs find themselves in a unique position. If they do filibuster the only way the White House can counter is with reconciliation. With that being the only option, there is no way dems are going to let health care die.
The problem is that if reconciliation is a definite possibility, I think some dems will be pissed off if the public option is not in the reconciliation bill. I will be pissed off.
