WASHINGTON (CNN) - Sixty. It's the magic number of votes Senate Majority Leader Harry Reid needs to move his health care reform bill to the Senate floor and tamp down filibuster threats by Republicans.
And the 60th vote could well be Sen. Ben Nelson, D-Nebraska.
Nelson and other Democrats have spoken out against the costs of plans being discussed, and most recently the $1.1 trillion House bill, which passed last weekend.
Reid doesn't expect Republican support for the bill, so he'll need all of the 58 Democrats and the two independents who caucus with them.
Nelson, 68, recently said he would decide how to vote on whether to send the bill to the Senate floor once he sees the final version.
"I'm not going to make any kind of commitment until I see the bill," Nelson said, adding that he has not given Reid any assurance or "secret" acknowledgment of support.
"I can't decide about the procedural vote until I see the underlying bill," he told CNN.
Nelson told ABC News on Tuesday that faced with a decision on whether to "move a bill that is bad, I won't vote to move it."
