If Senator Nelson is really dead-set against things like taxpayer-funding of abortion, it would make sense to vote against the motion on Saturday night. While there’s a chance language like the Stupak amendment could get 50 votes in the Senate, it can’t get 60 votes. Nelson can always vote against cloture at the end if the bill pays for abortions. But the Senate could get 60 votes for cloture without Nelson if Reid drops the public option and keeps its abortion-funding provisions, thereby potentially snagging the vote of Olympia Snowe. (Of course, that would also require self-proclaimed pro-lifer Bob Casey to sell out, and voting for abortion-funding could end the careers of senators like Kent Conrad, Harry Reid, and other Democrats.)
