Obviously they benefit. Don't be a moron. Ethanol power is bad for the environment, bad for consumers, and bad for downstream industries, corrosive to engines, and unpipable, and also requires more energy to create per gallon than a gallon of ethanol gives - there is nothing positive to be said about it. But while there is no doubt that it is bad for the nation as a whole, we are stuck with mandates for it. Why? Because Iowa is of importance in national elections as a swing state, where CA, already paying too-high gasoline prices, is generally not. Do you even use your brain before you post?
