That’s a little too much simplification there. Some is political, the problems with Iran and speculation that they may cut off their oil supply. But there is nothing political about the terrorists attack on the Nigerian pipelines. They have the light crude that is best for making gasoline, so that’s especially bad for gas prices.
Also, the MTBE ban is cause a big problem for gasoline. I guess that is somewhat political though because it was a bad political decision to ban it without a better phase out plan.
