So... we're not forced to buy ethanol at the pump, with the price subsidized (and made semi-competitive) by the general population's generous but involuntary contribution, at the behest if ADM?
How would I go about requiring 50 million people to buy my product, to the exclusion of my competitors, by Federal mandate?

Pay careful attention to the Iowa caucuses and primaries, in which the commercial item of greatest value to the businesses and citizens of the State is never discussed: corn subsidies.
