Is the number of Republicans supporting Baucus's bill, which is apparently going to be released today. The Hill reports that Snowe is now out. But hey, maybe Baucus can still get Enzi.
In all seriousness, I don't think this is the last word on Snowe. It could be kabuki on her part -- establish opposition now to provide political cover for later support. Of literally all the Senate Republicans, she seems sincere in her desire to get a decent reform bill. So I'm not giving up on her.
But that said, Baucus dragged out this process for months. In doing so, he exposed reform to all types of attacks. Yes, the attacks were inevitable, but the lack of a single bill limited supporters' ability to push back effectively. As of today, he has literally nothing to show for it.
