Lone Democratic dissenter Sen. Ben Nelson (D-Neb.) said he doesn't hold the decisive vote to bring financial reform to the floor, although he's waiting for a bipartisan agreement before budging.
Nelson, who has voted 'no' on each of the three cloture motions that would allow the Senate to begin debate, suggested counting the votes.
There are 59 Democrats -- West Virginia Democrat Robert Byrd didn't vote today -- so at least one Republican needs to defect to reach the 60 needed to move to the bill.
The count today was 56-42 with Nelson and Senate Majority Leader Harry Reid (D-Nev.) voting against the measure just so he can bring it up again.
But there's no pressure at this point on Nelson to change his vote, he told reporters Wednesday.
"It's my decision and I'm independent on voting and it has nothing to do with the way anyone else votes," he said.
Senate Republicans aren't likely to change their votes until either a bipartisan agreement is reached or negotiations reach a point where the only option is to bring the bill to the floor for debate.
Leading Republicans today suggested the latter will happen and they'll decide it's time for to begin debate on the measure.
