From last night's Daily Show - it's right at the end of the video embedded below the fold.
McCain: You tell any enemy when you're leaving, and they'll say, "Right, fine, we'll just wait until you leave and we'll take over."
Stewart: But that assumes that we're fighting one enemy...
McCain: That's not too complicated
Stewart: . ... they're fighting each other. It's not. We're there keeping them from killing each other. We're not surrendering to an enemy that's defeated us. We're saying, how do you quell a civil war when it's not your country?
McCain: I'm saying that we're paying a very heavy price...
[Massive audience applause interrupts him.]
McCain: I think I know...
Stewart: And the thing is the tickets... the tickets are free.
McCain: I think I know who's side they're on.
Stewart: No. They're on America's side, because they're patriots.
Thank you, Mr. Stewart.
