The Senate voted 68-31 to send gun legislation to the floor for debate. The majority included many Republicans who oppose the bill, but believe the issue should be debated. U.S. Sen. Mark Pryor was one of two Democrats who opposed the motion.
If I read this correctly, the NRA didn't set a litmus test on this particularly procedural vote. But Pryor voted against it anyway. The real tests are on filibuster of a compromise proposal to broaden gun background check purchases to gun shows and Internet sales, something widely supported among the public at large, but not by the NRA.
