A number of social, economic and political issues currently divide Americans more than they unite them. Does Senator Obama think it's possible to reclaim the American dream in our lifetime?
"Absolutely, I think it's possible. I think the country is ready for a constructive, hard-headed debate about how we move the country forward," he says. "I think the country's ready. I think it's a matter of leadership stepping up and giving people the opportunity to have this conversation. If we do, I'm very hopeful about the future of America ... and I'm so lucky to be a part of that process of trying to move it forward."
