I talked with a couple of knowledgeable sources about what’s going on now. Five Republicans, I’m told, have expressed some degree of interest in the bill: Ayotte, who would appear be a near-certainty to switch her vote; Flake, also a likely; Murkowski; Dean Heller of Nevada; and Bob Corker of Tennessee. Tennessee seems like a tough state to be from when casting such a vote as a Republican, but Corker is someone who at least tries once in a while to have conversations with Democrats.

On the Democratic side, as you’ll recall, four Democrats voted against Manchin-Toomey: Begich, Heidi Heitkamp of North Dakota, Mark Pryor of Arkansas, and Max Baucus of Montana. I’m told that Begich would like to switch, just needs to figure out how he can get there. Heitkamp is a bigger question mark. Pryor is probably lost.

That leaves Baucus. Shortly after the last vote, he announced he was retiring. That ought to mean that he should feel free enough to vote for the bill this time. It’s hard to know what Baucus actually believes—if that matters. He has a solid NRA career rating, but he’s cast enough votes the other way (supporting the assault weapons ban and the Brady waiting period) to make the other side suspicious. Before he announced he was quitting, the NRA was running ads against him.
