What happens when a campaign committee goes bust?

[rhu]

I was reading in the Times the other day that Giuliani's campaign committee has about $1.2M in debt that they may be unable to retire. I wonder: how does that interact with campaign finance laws? If I loan my favorite candidate's committee millions of dollars, and they are later able to fundraise that amount from hundreds of thousands of $2300 donations, everyone's happy. But if I loan the committee millions of dollars, and they later go bankrupt and default on that loan, how is that treated by the campaign finance laws? Would I not have, in effect, made a multi-million-dollar contribution to the candidate's campaign?
