GEORGE STEPHANOPOULOS (co-moderator): I want to give Senator [Hillary] Clinton a chance to respond, but first a follow-up on this issue, the general theme of patriotism in your relationships. A gentleman named William Ayers -- he was part of the Weather Underground in the 1970s. They bombed the Pentagon, the Capitol, and other buildings. He's never apologized for that, and, in fact, on 9-11, he was quoted in The New York Times saying, “I don't regret setting bombs. I feel we didn't do enough.”
An early organizing meeting for your state Senate campaign was held at his house, and your campaign has said you are friendly. Can you explain that relationship for the voters, and explain to Democrats why it won't be a problem?
