You still have it wrong, the second bill was closer than the first, meaning the dems and rinos picked up another 13 votes in favor of the cloture motion. If the cloture vote passes debate ends and a move to final passage occurs which only needs 60 votes to avoid a filibuster and 51 votes to pass if a filibuster fails. In such a case the votes usually fall along party lines with the dems picking up at least a number of rinos. I count McConnell, McCain, Collins, Hagel, Graham, Specter, Lugar, Domineci, Voinivich, Snowe, Craig, Bennett, Murkowski, Stevens and perhaps Kyl as possible votes for cloture in the end.
