Actually, a successful cloture (60%) is not needed, if unanimous consent w/o objection is given. No one goes on record for that. Further, a successful cloture vote is a vote to stop debate, forcing an immediate vote. Sometimes, a member votes for cloture and then votes against the measure. Soooo, technically, it only takes 50% + 1 of Senators present to pass a measure its first time. If the measure suffers a presidential veto, it must survive the second time with, at least, a 66.67% majority of members present on both sides of Congress, lest it fail.
Provide one or more Senators do not decide to Filibuster.
I think that is fantasy on this hot-button topic.
