I would rather he reverse his vote on the bill, being the lone Dem who votes against it and kills it, then gets re-elected in a landslide in 2012. All in all I think it would be a better outcome.
Nope, cloture was the vote. He can reverse his vote now and it will still pass. He already did the dirty deed by voting for cloture, voting against the final bill is just attempted CYA and pure hypocrisy.
