Found this watching old debates on C-SPAN yesterday. Includes prescient comments from Biden that predict the larger regional conflict, and he makes his argument for Balkans-style devolution of power. Senator Obama makes excellent follow-up remarks, and Senator Clinton awkwardly reaches for a glass of water as she's called out.
A really special moment, and one that proves how much more lively and intellectually engaging primary debates are when compared to debates in the general election.
