Georgia senator said to be working to revive gun control

The Washington Post says two Republicans have signaled willingness to help revive the senate debate on gun control. The Post cites Senate aides and spokespeople:

The aides, who asked not to be identified because they were not authorized to publicly discuss the talks, refused to identify the two Republicans. 

But through spokespeople, Sens. Johnny Isakson (R-Ga.) and Jeff Flake (R-Ariz.), who voted to block the background check proposal, signaled they are open to a new debate if Democrats make significant changes to the plan.

Harry Reid still collecting favors for taking Isakson along on that plush China trip two years ago? Would be gun grabber Chuck Schumer was also part of Reid's China delegation.

Update: For the folks back home, Isakson's people seek to distance him from a Toomey-Manchin revival. If that's the case, why can't Johnny leave well-enough alone?
