You need 60 votes to be filibuster proof. When’s the last time the RNC had that?
The bill McCain cosponsored passed in committee, all Republicans voting for, all Dems against. Was the threat of filibuster the reason it did not go to the full senate for a vote? Seems like from what I read the reason given was simply that there was not enough votes in the senate to pass it. I suspect that a few (or more) Rinos sided with the dems.
