So, over 2 million farms is a few? Do you farm? What business are you in? Show me the calculations on corn that generates 400 gallons of ETOH/acre, a high protein livestock feed and cornstalk forage is a net energy loss. If you can show the science based evidence then I can be persuaded, but the big oil companies can’t produce them either, since they always omit the feed and forage from consideration. They also never mention that growing corn is a CO2 sink and an efficient user of sunlight to make portable energy.
We're talking Iowa, here. There are only 75,000 family farms left in Iowa. Even counting 2 voters per farm, that's only 7% of the voting age population in Iowa.
Here's a link from Texas A&M university, indicating a net energy LOSS for generating ethanol from irrigated corn:
