The 11 House Democrats led by Rep. Bart Stupak who dropped their opposition to health care reform legislation mere hours before the final vote have requested $3.4 billion in earmarks -- and one watchdog group wants to know whether the money represents business as usual or political payoffs. 

The Sunlight Foundation says it plans to track the earmark requests, which were put in one day after health care reform cleared Congress, to see whether they're approved and whether it appears lawmakers are being rewarded for their vote. 

"We know that in Congress one of the ways that leadership tries to influence members is through earmarks," said Bill Allison, editorial director at the nonpartisan organization. "So this seemed to us something good to follow." 

Stupak and the 10 other Democrats were critical to the success of the health care bill. They were holding out over concerns about funding for abortion coverage but announced the president had assuaged their worries -- with an executive order restricting abortion funding -- the morning of the big vote. 

Stupak's office said there's absolutely no link between the earmarks and the health care bill's passage. 

She also said his earmark requests this year are in line with prior years, in number and in total amount.

But watchdogs want to know whether there's more to the story. 

Since the health care reform push hit its final stretch, numerous sweeteners for lawmakers' districts and states have been found inside the package. Earmark requests are made outside of the health care bill, making them a bit more difficult to link to any vote-trading. But it is precisely that kind of tricky-to-catch deal-making that Republican Sen. Tom Coburn said he and other GOP senators would be monitoring for months to come. 

"If you think you can cut a deal now and it not come out until after the election, I want to tell you that isn't going to happen," Coburn said a few days before the bill passed. 

Lawmakers like Stupak have since been heavily scrutinized. Allison said the lawmakers who stood with him will find out if those earmarks are approved when the Appropriations Committee's bills come out in June or July. 

The individual earmarks requests from each of those lawmakers range from $20 million to $1.4 billion. Of the eight lawmakers whose 2010 requests were available for comparison, five requested more money than they did a year ago. Stupak requested $579 million. 

Here are the earmark amounts requested by the 11 House Democrats in the 2011 bill: 

Rep. Jerry Costello of Illinois.: $1,418.7 million ($256.4 million in 2010)

Rep. Solomon Ortiz of Texas: $618 million ($726.1 million in 2010)

Stupak of Michigan: $578.9 million 

Rep. Steve Driehaus of Ohio: $332.2 million 

Rep. Marcy Kaptur of Ohio: $294 million ($305.7 million in 2010)

Rep. Kathy Dahlkemper of Pennsylvania: $236.8 million ($54 million in 2010)

Rep. James Oberstar of Minnesota.: $207 million ($226 million in 2010)

Rep. Brad Ellsworth of Indiana.: $115.4 million ($82.3 million in 2010)

Rep. Charles Wilson of Ohio: $84 million ($62.3 million in 2010)

Rep. Paul Kanjorski of Pennsylvania.: $67.1 million 

Rep. Joseph Donnelly of Indiana: $19.8 million ($11.65 million in 2010)

The Sunlight Foundation also says it is going to look at Republican earmarks. House Republicans say they are not requesting any earmarks for the next fiscal year, but Allison said the Sunlight Foundation will watch GOP senators to see if they appear to be putting in earmark requests for their House colleagues.
