INCREASING ETHANOL IN GASOLINE IS FUCKING STUPID AND WILL MAKE AMERICA POOR AGAIN
Here's why:
Subsidies are bad economic practice.
If you were to subsidize farmers to create biofuel (which is what ethanol is), you get a much better return if:
-You grow either hemp or switchgrass
-You extract oil and use it for diesel (hemp)
-You take the hemp byproducts/switchgrass and convert it to bio-butanol (a drop-in replacement for gasoline that is much less corrosive than ethanol).

Using CORN for ethanol is fucking stupid b/c:
-You get 1.1 energy units out compared to what you put in
-Time & human energy spent growing food and burning it is stupid
-Ethanol is corrosive and destroys older vehicles, causing the poorest among us to either repair or replace a vehicle sooner than necessary.
Better yet, let farmers create biofuel from hemp and swtichgrass, and let them sell it tax free. Watch the market explode. Farmers make money. Consumers get cheap fuel. China can suck it. Win win win.
