What question would you ask the Democratic Candidates?

The You Tube/CNN debate led me to think about what question I would ask. Here's my nomination for a question:
Have you seen Michael Moore's documentary ("SiCKO") and what do you think of his critique of the American health care industry?
Here's my nomination for a foreign policy question:
How many troops would you plan to leave in Iraq and how would you plan to protect them?
Any suggestions????
