Joe Biden claims that five Senators want to change their votes on background checks

Joe Biden keeps pushing on gun control.  It is amazing that Biden claims that there are five Senators who want to switch their vote on background checks when they need to pick up six votes to have Reid bring up the bill again (the original vote was 54 to 46).  As of right now it is a claim that he will never have to prove.  From Politico:

. . . Speaking to the U.S. Conference of Mayors in Las Vegas, Biden said the 45 senators who voted to block the background checks deal brokered by Sens. Joe Manchin (D-W.Va.) and Pat Toomey (R-Pa.) have seen “the bottom fall out” of their approval ratings. 

Biden said, as he did Tuesday during a gun violence event at the White House, that he has been fielding calls from senators interested in signing on to some kind of gun control measure. On Friday he offered slightly more specific detail about the number of senators and the difficult path ahead for gun control legislation. . . . 

“I’ve had at least five senators call me and say, ‘Can’t we do something about this?’” Biden said. “The calculus has changed, and so we’re in an effort to try to work out how we can provide another opportunity for those who voted no to change their vote. We all know that’s the hardest thing in politics, to change your vote. That’s why we’ve got to get a rationale, another reason why this could be done by changing the specifics of the legislation.” . . .
