You jumped the gun. This is the vote for cloture, not voting for the bill!!
A vote for cloture is essentially a vote for the bill to pass. The Dems have more than enough to get the 50 votes they need. Don't be tricked by Specter and the Mainettes voting for cloture and then voting against the bill to give them some cover. I wouldn't be surprised to see Reid allow a few of the more vulnerable Dems to vote against it to provide them cover. But make no mistake, everyone who voted for cloture (with the exception of Corker's procedural vote to maintain the right to have a revote) did everything they could to get Porkulus passed.
