The facts are simple.
Gas Prices under George W. Bush reached $1.90
Gas Prices under Obama are above $4.00.
Correction: The prices under Bush did get to $4.00 for a brief period. He then took action to open drilling in the gulf and other areas and the price dropped. This president would rather we wait till someone invents a car with a windmill on top and we all buy into it.
I recall when it was actually under a dollar in Bushes first term.
W was the prime mover in terms of high gas prices, a weak dollar, large corporate bailouts, and a bad economy. Obama hasn't made it any better, though.
Gas prices did temporarily collapse under W in 2008, but that was due to an impending global economic collapse.

Gas prices got into the $4 range during the summer of 2008. However its important to note that democrats held both the house and senate but went on vacation and refused to deal with energy policy.
My congressmen was one of those who stayed in Washington calling for Nancy Pelosi to call congress into session to deal with the situation. Gas was the single most expensive cost of my trip up north that summer.
