The only reason we have ethanol in our gasoline is because of the power of the farm belt corn lobby. From Eric Peters at theburningplatform.com:
The corn lobby – which benignly styles itself The National Corn Growers Association – is upset with the Orange Man for – as CNN puts it – “reducing demand” for its crops.
What he’s actually done is reduce the mandate for them by granting waivers to refineries which would otherwise by forced by a federal law called the Renewable Fuels Standard or RFS to douse the gas they make with ethanol – which is made (in the United States) using mostly . . . corn.
