We have more oil under our ground than we can dream of. We don't need to turn corn into biofuels. God intended that Corn be turned into whiskey and corn flakes.
And American domestic oil extraction/production is also subsidized so don’t kid yourself.
IIRC those subsidies were ended. If they weren't then they need to be.
We have had subsidies for ethanol since Ronald Reagan - who supported them by the way. Sorry, this is not a hill any of you should die on.

The oil that is underground is not cheap to get to oil. If oil is below a certain price it is not cost effective to get it out of the ground. I support subsidies for this as well - because it leads to independence from foreign oil.
