Ben Nelson released an ad Wednesday defending his vote to block a Republican filibuster of the health care bill."](CNN) - Nebraska Sen. Ben Nelson, the conservative Senate Democrat who provided the party with the 60th vote needed to prevent a Republican filibuster of the health care bill, is defending his move in an a television ad set to air Wednesday.
The ad, to run during the sure-to-be highly rated University of Nebraska's Holiday Bowl game Wednesday night, features Nelson himself directly explaining to constituents why he voted for the measure the recent polls of have suggested is unpopular with most Nebraskans.
According to the Lincoln Journal-Star, Nelson will tell constituents he worked hard to improve the controversial bill before committing to be the Democrats' crucial 60th vote.
"Now it lowers costs for families and small business, protects Medicare, finally guarantees coverage for pre-existing conditions and reduces the deficit," Nelson says in the ad, according to the paper. "And it's not run by the government. I'm convinced this is right for Nebraska."
As part of his agreement to vote with the Democrats, Nelson successfully negotiated the federal government to pay in perpetuity for Medicaid's expansion in his state, an agreement that has riled other senators whose states have to foot the bill.
Nelson told CNN shortly after the vote he did not seek any special favors.
"I didn't ask for a carve-out," Nelson told CNN Chief National Correspondent John King. "What I said is the governor of Nebraska has contacted me, he said publicly he's having trouble with the budget. This will add to his budget woes. And I said, look, we have to have that fixed."
Nelson won't face reelection until 2012.
