heated debate between Krugman and Scarborough

Watched the heated debate last night in PBS between Paul Krugman (Nobel prize laureate in Economics) and Joe Scarborough about the U.S. debt and deficit issues. As expected, Krugman was pretty brash but his ad hominem attack was quickly refuted by his opponent. As always, "You are absolutely wrong and I am totally right" attitude only makes the debate more polarized than ever.
