Forbes reports the dubious distinction for Newt Gingrich as he emerges from the '12 primary with $4.3 million in campaign debt.
That's far more than Rick Santorum, who only accrued $1.9 million and places fourth on the list.
THE LIST of politicians with the most campaign debt, as of March 31. 2012:
1. Newt Gingrich $4.3 million
2. Lyndon LaRouche $3.2 million
3. Rick Santorum $1.9 million
4. Rudy Giuliani $1.5 million
5. Jon Huntsman $1.3 million
6. Michele Bachmann $1 million
7. Al Sharpton $896, 213
8. Dennis Kucinich $557,383
9. Alan Keyes $483,020
10. Rep. Laura Richardson (D-CA) $439,785
Richardson is the only candidate on that list who hasn't run for president, and Forbes notes the curious circumstances surrounding it.
The congresswoman from California’s 37th district is the only member of this list whose campaign debt didn’t come from a presidential run and is also unusual for amassing such a large backlog of unpaid bills in elections with only token opposition. She won her congressional seat in a 2007 special election and successfully defended it in 2008 and 2010 with 75% and 69% of the vote, respectively.
