Campaign Debts
I'm not really sure that an offer to retire Hillary Clinton's campaign debts would have a ton of appeal to Clinton. It seems to me that once she's out of the presidential race, she'll still be a fairly influential U.S. Senator who shouldn't have much trouble raising funds from folks looking to curry favor with her, and she's unlikely to face a serious 2012 challenge so her re-election fundraising can just go to pay off presidential campaign debt.
