Every time I stop at a gas pump (and bear in mind that the gas at the "unbranded" convenience store and the gas at that fancy "big name" station across the street may come from the same batch at the same refinery piped to the same terminal, at best delivered by a different tanker truck). I'm angered to see that my fuel contains 10% ethanol. 85% would really raise my ire.
Do we not understand that for every gallon and for every mile traveled that ethanol requires substantial energy (burned hydrocarbons) to produce, costs more (if 'economic" at all, only due to a variety of subsidies involved in its production), and drives up the price of corn, not just the corn products used in your kitchen, but with a harsher toll, the price of the masa used in low income households to make the "staff of life" among the poor, tortillas.
We have been fed a "Grand Illusion", far more costly than a dozen Keystone Pipelines pumping that nasty, dark, thick (but quite refine-able, even into high octane AVGAS) Canadian sludge down to Gulf refineries.

Selfish? Of course I'm selfish, but then recently I drove by a piece of land where a combine was busily harvesting corn. Now, I "own" a little chunk of the mineral rights beneath that particular land, the geologists, often right, claim that oil and natural gas await down below, deep and expensive, but if the farmer and ADM, Cargill, etc., are going to use that corn to help fill their coffers and the tank on my gas-guzzling SUV, why shouldn't somebody drill for oil to replace the corn (so you can have sweet soda pop, those poor Mexican children an extra tortilla or 2, and I can receive a monthly royalty check)? I'll even agree to let'em use the natural gas to boil up corn mash to make alcohol, preferably drinkable ethyl, not burnable ethanol.
