Who Gouges on Gasoline?

According to George Will, it's Uncle Sam and his nieces and nephews (local and state governments):

While oil companies make about 13 cents on a gallon of gasoline, the federal government makes 18.4 cents (the federal tax) and California's various governments make 40.2 cents (the nation's third-highest gasoline tax). [House Speaker Nancy] Pelosi's San Francisco collects a local sales tax of 8.5 percent -- higher than the state's average for local sales taxes.
