Clinton maintains $15 million debt

Secretary of State Hillary Rodham Clinton paid off $8 million of the debt she incurred during her run for president, but she still maintains $15 million in obligations, according to Federal Election Commission (FEC) filings.

Most of the payments went to rid the campaign of credit card debt, though the campaign also paid back taxes owed to the IRS.

The campaign also paid thousands of dollars to a Palo Alto, Calif., Web consulting firm that designed the campaign's website.

Eight staffers remain on Clinton's payroll, the filings show.

The rest of Clinton’s outstanding debt is owed to Penn Schoen & Berland, the market research and consulting firm headed by Mark Penn. During the campaign, Penn served as Clinton’s chief strategist until the final months of the primary season, when he was replaced by Democratic pollster Geoff Garin.

Clinton's campaign paid off more than $800,000 in back debt to Penn's firm over the last three months, the FEC reports showed.

Several other former presidential candidates remain in debt. Former Massachusetts Gov. Mitt Romney (R) still owes himself $250,000 after converting millions of dollars in loans into direct contributions. Sen. Chris Dodd (D-Conn.) owes almost $300,000 to a number of vendors.

Former Arkansas Gov. Mike Huckabee (R) also maintains a small debt.

Ex-Sen. John Edwards’s (D-N.C.) 2008 presidential campaign is debt-free, but his 2004 campaign still shows $333,000 on the books — including more than $64,000 owed to Axelrod & Associates, an early incarnation of strategist David Axelrod's consulting firm. In 2008, Axelrod went to work for President Obama instead of his former client.
