New Obama Ad: "Tested"

McCain's mortgage plan would force us the taxpayers to buy bad bank loans at full value -- no matter what the value of the property is. So if a bank loaned a homeowner $300,000 to buy a house that's now worth $200,000, we the taxpayers would pay $300,000 to the bank for a $200,000 house. Net profit to the crooked bank: $100,000; same net loss to us. A terrible plan. I don't think this ad explains it very well.
