Very true. Yeah the whole corn to fuel is really weird. Why not just use oil? I know it was the Democrats who screwed that up like they screw up everything they touch.
As for the corn crop necessary for ethanol, Latino cultures and nations pay noticeably higher staple corn prices because of the reduced corn supply. Switching Iowa to food corn production would help to lower that commodity price, Iowa is highly productive. However, I do not know if Iowa would receive as much as for the subsidized fuel crop.
