On Thursday, the US Senate voted on the Manchin-Toomey gun control bill. The bill, which would have required background checks on guns sold at gun shows and online, failed on a 48-50 vote.

Ron Johnson somehow managed to miss the vote on this bill, even though he voted on the proposals just before it or just after it. Maybe he had to go to the bathroom. Maybe he remembered that he left the coffee maker on in his office. Maybe he had to call the Kochs to find out how to vote.

Or maybe, as Scot Ross of One Wisconsin Now points out, RoJo was just afraid to cast a negative vote just before an election year:

His critics were quick to jump on his absence. The Democratic Senatorial Campaign Committee called him a "glaring no-show."

"To quote his 2010 commercial, 'There are 100 members of the U.S. Senate,' but only Ron Johnson hid in the Senate cloakroom to avoid a tough vote on guns," said One Wisconsin Now executive director Scot Ross. "Tea Party Senator Ron Johnson opposes closing the loophole in our law that lets guns be secretly sold by private sellers with no background checks and no questions asked. But it's election time and politician Ron Johnson is trying to save his own hide by cutting and running on a tough, high-profile vote."

I certainly hope that RoJo doesn't think that running like a scared kitten from the tough votes is going to help him next year when Russ Feingold trounces him in next year's election.
