The House Blue Dogs, the fiscally conservative group of 51 House Democrats, have raised more than $1.1 million for their political action committee this election cycle, putting it on track to break all previous fundraising records, according to a new report by the Center for Public Integrity.

"Whether the subject is health care reform, climate change or pay-as-you-go budgeting rules, almost everyone, it seems, suddenly wants to talk wtih the Blue Dogs," the Center said. "As their clout has expanded, fundraising has grown too."

The study also found that nearly 54 percent of the Blue Dog PAC's contributions this year have come from three sectors: health care PACs, energy PACs, and financial services PACs.
