Today, House Speaker John Boehner revealed his selection of Republican representatives to serve on the 12-member Super Committee in charge of slashing $1.5 trillion in federal spending. The appointments include congressmen Jeb Hensarling, Dave Camp and Fred Upton. Since the Super Committee is going to be the biggest lobbying bonanza in Washington for the next three months, we thought it'd be nice to know what corporations and advocacy groups have been filling the respective committee members' campaign coffers over the years.

Dave Camp The top industries feeding this Michigan Republican are health professionals, insurance, pharmaceuticals and chemical manufacturers, according to the non-partisan Sunlight Foundation. He has the fortune of being born in the same town that Dow Chemical calls its home, Midland, Michigan, and it shows in the list of his contributors with Dow Chemical on top with $278,044:

Fred Upton Another Michigan Republican, the top industries giving to Upton include health professionals, retired people, pharmaceuticals and electric utilities, according to the Sunlight Foundation. Upton doesn't have a single contributor that far outpaces the rest (Ford, Whirlpool and the National Association of Broadcasters each give him between $85,000 and $70,000) but he does have a somewhat high ratio of PAC money to individual donor money:

Jeb Hensarling The top industries bankrolling this Texas Republican include commercial banks, finance, insurance and securities & investment. He gets a lot of PAC money from the professional services firm Kpmg Lip ($52,250 total) and also has First State Bank, American Bankers Association and the National Beer Wholesalers Association as top contributors.
