Former Sen. Rick Santorum, R-Pa., who won the Iowa Republican caucuses and 11 state primaries in his 2012 presidential campaign, still has $552,895 in debts outstanding.

Although he has spent the last three days in Iowa, his 2013 fundraising has been almost nonexistent. His $138,396 in receipts in the first six months have been mostly from renting his donor lists out to others. For example, Patriot Voices Inc. (Pa.) paid the presidential campaign committee $75,000 as a partial payment on a list purchase. His presidential committee has $11,660 in cash on hand as of June 30.

His expenditures this year have been mostly monthly installments to pay down his debts to vendors. As of June 30 his campaign owes Brabender Cox (Pa.) $398,905 for media, consulting production and placement of ads; $43,379 to Emotive LLC (Va.) for website/online advertising and email services; $38,880 to Victory Phones (Mich.); $32,477 to Biter Enterprises (Fla.) for air charters; and $10,000 to Front Row Motor Sports (N.C.) for a car sponsorship; among others.

Santorum is now CEO of EchoLights Studios, which “produces and distributes high-quality movies for families of faith.” The company is based in Dallas.
