Jonathan Chait is enjoying what you might call "pre-schadenfreude" about health care's apparent revival. One can understand the urge, given how little opportunity liberals have had to actually revel in GOP despair over the past few weeks. But I think it's more wishful than warranted.
Despite having declared the death of the health care bill before almost anything else, I don't want to say that the thing's impossible. But the House has lost three of the votes it used to pass their bill 220-215 . . . which means that you have to persuade someone (probably a Blue Dog) to vote for it, who already voted against it. Progressives have been making the almost-plausible argument that the public is going to treat a vote for the House or Senate bill as a vote for final passage, so Democrats might as well go ahead and pass the thing. But their best argument totally falls apart for those who originally voted no.
And that's the best case scenario. It assumes that you can keep Bart Stupak's pro-life caucus, even though it's unlikely that they'll be able to "fix" the Senate's more liberal abortion language in reconciliation. This is a pretty heroic assumption. If you lose many of the Stupak folks, then the bill's done; there is not a snowball's chance in hell that you are going to persuade any significant number of the prior "no" votes in the Democratic caucus to throw their careers on the pyre of Democratic health care ambitions.
