How is Obama going to manage in a debate versus McCain?

McCain schools him on foreign policy and knowledge of the war. And there isn’t exactly an issue Obama knows more about than McCain to compensate.

And saying change through the debate isn’t going to last up till November. Does Obama have an advantage in a debate, if any, against McCain?
No one answered the question with an advantage he’d have during the debate. You all just have faith in Obama and don’t even know why.
