Does he do it with a jawbone of an ass?
It is clear the Borosage needed to rely upon complete falsehoods in making his "presentation". Saying that the problems were caused by the free market and that Schiff was an advocate of the housing boom puts him in the league with DeLong and Krugman. People who must lie constantly clearly have no truth to tell.
Of course Schiff is right, but I don't know that he was able to convince anyone in this short appearance. He has a rare talent for revealing the absurdity of Keynesianism, often using simplified illustrations (Crusoe economics, etc.), but he's mostly just asserting his premises here without explanation. The crooksandliars website (where this clip is hosted) sides with the 300 "economists." But that's a left-wing website anyway.
