The problem for the ethanol lobby, is that the same thing happens that always happens with the government subsidy. Sharp operators have moved in and sucked up all the money. This concentrates the subsidy with a very small number of individuals. They care about this issue a lot, but each one can only vote once. They are victims of their own success.
.
ADM just sends the subsidy money back to the guys that voted for it through lobbyists.
Crooked congresscritters get to pay themselves.
