Here's a look at how senators voted on the Thune Amendment.
Lots of Western and Southern Democrats voted for it, including Majority Leader Harry Reid (up for reelection in 2010).
Video: Despite support from some Democratic senators, the Senate struck down a bill Wednesday that would have allowed gun owners to carry concealed weapons across state lines. NBC's Kelly O'Donnell reports.
Some others that stand out:
Russ Feingold (up for reelection in 2010) voted for it. Feingold said in a statement: "Last year, the Supreme Court finally recognized that the right to bear arms protected by the Second Amendment to the Constitution is an individual right. Americans' right to possess a firearm to protect themselves or their families does not stop at a state border. Once citizens have obtained permission from a state to carry a concealed weapon, they should be able to rely on that permission in states that permit the concealed carrying of firearms, and that is why I will support the Thune amendment."
Arlen Specter voted against. As the National Republican Senatorial Committee points out, this puts Specter to the left of the other Pennsylvania senator, Bob Casey, who voted for it.
Two Republicans voted against: Richard Lugar and George Voinovich (retiring). And that means the Republican from Indiana is to the left of the Democrat on guns. Evan Bayh, the junior senator from the Hoosier state, voted for it.
Most of the votes fall along predictable geographic lines.
Here's the full roll call:
