The critical component, though, is a mechanism that would force senators to physically take the floor and speak in order to maintain opposition to legislation. The effort to end a filibuster is called a cloture motion. Under the proposed rules, if a cloture vote failed to win a simple majority, the bill would be killed and the Senate would move to new business. But if it won a majority – though less than a supermajority of 60 – the bill would remain on the floor for any senator who wished to opine on it. If at some point no senator rose to speak, after given several chances to do so, a new vote would be called – and only a simple majority would be needed to pass it.
