I'm going to have a hard time supporting the guy in the primary.
Ethanol subsidies, like other agricultural price supports, are reverse-robin-hood: they take from the poor (us) and give to the mostly rich (large farms and Big Ag).
Here's an idea: how about we let ethanol follow market forces. If no one wants the stuff, there will be less produced, and farmers can plant wheat and barley instead, to make proper methanol.
