AP reports John Edwards’ presidential campaign owes more than $2.1 million in taxpayers’ matching funds.

Though Edwards dropped his presidential bid in 2008, “it’s not unusual for presidential campaigns to remain open years after the election is over, especially if there is an unresolved audit or unpaid debts.”

But check this out:

Edwards’ campaign reports show more than $15,000 spent in 2011 on airfare, though the destinations or purpose of the travel were not listed. In January, August and December, the campaign spent $2,268 for tickets on Alaska Airlines, a transcontinental carrier that does not offer flights between East Coast cities such as Raleigh or Washington.

Most of the $12,811 in credit card charges for lodging were made to websites such as Hotels.com and Kayak.com, providing no information about where the rooms were booked, when or for what purpose.

When contacted by AP, nobody involved in the campaign seems to know anything.
