Can anyone name one thing that John McCain has done to prevent this economic crisis from happening?

Barack has opposed the war in Iraq since its began. That is what has gotten us into this economic crisis, that and bad trade agreements made by the Bush administration, for those of you who argue its not, then what in your mind has? For those of you who argue that the gas prices is what has caused this economic crisis, what is it that you think caused demand to go up and supply to shrink? Could it be the war? Bush running Chavez out of town telling him we didn't need his oil?
