So Obama is running about saying that 3 million more people would have been unemployed if it wasn't for the trillion dollar stimulus. He may be right. It just means it cost over $200 thousand per job saved.
If the stimulus actually worked, it should have saved 12 million jobs. If it had managed that then it would have been hard to argue that it didn't work. It didn't so it is a failure. Maybe Sarah needs to help him do the math because it's not exactly his strong suit.
