KRUGMANBLOGGING isn’t part of InstaPundit’s regular diet — in fact, this site has been Krugman-free for weeks, if not months. It used to be Kaus and Sullivan who did most of it, but lately Donald Luskin seems to have picked up the ball. I can’t vouch for this post’s veracity, as I haven’t followed the debate. But its ferocity is certainly something to behold.
