link didn't work for me so i didn't know the context. if he blamed tax cuts and war spending for the recession then yeah, that's wrong and not even a plausible explanation.
THE CLAIM: Biden Claimed The Recession Was Caused By The War Spending, Medicare Drug Benefit, And Tax Cuts. BIDEN: “And, by the way, they talk about this Great Recession if it fell out of the sky, like, ‘Oh, my goodness, where did it come from?’ It came from this man [Ryan] voting to put two wars on a credit card, to at the same time put a prescription drug benefit on the credit card, a trillion-dollar tax cut for the very wealthy. I was there. I voted against them. I said, ‘No, we can’t afford that.’” (Vice President Joe Biden, Vice Presidential Debate, Danville, KY, 10/11/12)
