Fifty-seven 'Rats, plus Snowe, Collins, McCain and Specter.
They already have 61 votes.
Specter voted the right way on most filibusters. Trying to paint McCain as a far-left liberal is insanity. He has an 84% ACU rating. Snowe and Collins are a problem, but you can count Ben Nelson (D-NE) on our side.
In any case, handing them additional seats is not wise. I don't know why so many so-called Conservatives are willing to do it.
Including handing off Chambliss, who has a 94% ACU rating, so he can be replaced by a leftist slime-ball.
Snowe thinks of no one else but Snowe, always has. It is highly doubtful that that affliction has a cure.
