Senate Republicans turned to the nuclear option Wednesday, voting to cut off debate, end a Democratic filibuster and override Missouri Gov. Jay Nixon’s veto of a voter ID bill. The maneuver, known as “calling the previous question,” has historically been rarely used — only 15 times since 1970. But in recent years Republicans have increasingly used it to force through bills that have garnered vehement Democratic opposition, including earlier this year when they killed a nearly 40-hour filibuster of a “religious freedom” amendment to the state constitution. That was the case Wednesday on a bill that would require Missouri voters to provide a government-issued photo ID before being allowed to cast a ballot.
