Comment: I would prefer Bob Murphy,

I would prefer Bob Murphy, especially since that a debate between Murphy and Krugman is already trying to be set up and especially since Krugman recently wrote about Murphy in his blog. But if Murhpy was not available, my next choice would be Tom Woods. If he wasn't available, my next choice would be Hans Hermann Hoppe (actually, now that I think about it Hoppe would be my first choice). Then Marc Faber. Then Jim Rogers. Then Dan D'amico. Then Walter Block. Lew Rockwell. Ron Paul (he already debated him quite successfully). That one Austrian Spanish economist (I forget his name). I love Peter, but he would be on the bottom of my list.
