Destroyed? I guess it depends on perspective. I’m not a particular fan of Krugman’s tactics. Too ideological. A bit dismissive of the tiniest bit of evidence countering his arguments. But his larger view of the european economy over the last 4 years has been spot on, and results have been as he predicted.
If you think Ron Paul kicks ass in every economic debate, then maybe Krugman got destroyed. I’ve never seen that. Nor did I see any destruction in this debate. Two varied approaches to economics. One pretty conventional. One a joke.
