Congress's corny con - Don Surber has the story on "ethanol's license to pollute." It turns out that the majority of refineries for ethanol violate clean-air regulations, so corn-fed Congressmen will take action by relaxing those pesky regulations. As I've said before: if America was truly serious about alternative fuels it would lift tariffs on sugar-cane ethanol from Brazil. But Iowa has the first caucus in the nation, so you'll not find a politician willing to state the obvious.
