Is this a surprise? Energy is highly political. In the midwest you get votes by supporting ethanol/corn. In california you get votes by supporting solar and wind. In florida you get votes with the anti-castro lobby by putting a tariff on foreign sugar and ethanol. In texas, you get votes for supporting oil. The biggest political problem with biofuel is that it would probably be cheaper to grow the crops in other countries, and that's not going to get you any votes.
