I think it's ridiculous that people were blaming Bush just as it's ridiculous that they are blaming Obama.

It went from about $1.50 to over $4 under Bush in the exact same amount of time it has gone from $1.85 to just about $4 under Obama. Neither one has had much to do with the change in prices (up or down). It's Iran, it's speculators, it's China and India.
