Oh...now it's not about damage to engines and Obama...now it's about cost and the availability of corn. I see. Move the goal posts when challenged, right?
Ok...let's move the goalposts and see what happens:
Ethanol is competitive with the cost of producing a gallon of gasoline, without a subsidy, when oil is above $70 per barrel. It is, and has been for some time.
The Biofuels FAQs: The Facts About Biofuels: Ethanol
Availability:
In 2011, the US produced 316,165,000 metric tons of corn. We consumed 281,100,000 metric tons, for all purposes including ethanol, which left 59,700,000 metric tons for export...a surplus of corn.
The whole world produced 816,006,000 metric tons, but consumed 836,118,000 metric tons, for a shortfall of just over 20 million metric tons. That's good news for American farmers, and especially in light of the fact that we COULD produce as much as 15 BILLION bushels by 2020 if we wanted to. The market will probably dictate that we will (you DO believe in the free market, don't you?)

Bottom line? We can produce it, we can afford it, if used properly it won't damage our engines and, along with the vastly increased production of oil and gas under this administration, we will become a net EXPORTER of oil and gas within a decade or so.
Why do you have a problem with that?
