Harry Reid bought his 60th vote from Ben Nelson with some preferential treatment for Nebraska (a few hundred million dollars over three years). Apparently, the bribe somehow changed Nelson's deeply held views on the issue of abortion.
Here's the greatly anticipated managers amendment. You should read it, your senator probably won't.
Nelson: “I reserve the right to vote against the next cloture vote if there are material changes.” But they won't need his vote...at that point, they only need 51, not 60.
It's all but a done deal.
