Probably only 54 get to vote on cloture, after Sen. Ensign's car accident. Still, if the 7 Ds of the Gang of Fourteen hold together and vote for cloture we have at least one more than the 60 votes required to squelch the filibuster.
Nelson of FL is hedging his bets and will vote for cloture and against Alito on final confirmation, so you can add one more to your tally.
