Senator Obama, Senator McCain,

As you know, under the Bush administration unregulated credit default swaps–which billionaire Warren Buffet describes as “financial weapons of mass destruction”–now exceed $40 trillion. Can you explain to the American taxpayer

a. What a credit default swap is;

b. Why credit default swaps are currently unregulated;

c. How a company with $1 billion of outstanding debt can have $10 billion of outstanding CDS contracts and;

d. How a default on $1 billion in corporate debt, assuming debt recovery at 40 cents on the dollar, becomes a $6 billion loss to credit default swap sellers.

Oh, and a follow-up if I may: What are your plans, if any, to regulate the CDS market in the future? Please be as specific as possible in your responses.

Thank you.
