Iowa is the the ethanol capital of America. Every politician seeking the Presidency pays homage to the Iowa caucuses and promises to maintain all the government subsidies and tariffs that keep this greenie boondoggle alive. Palin could schedule an appearance in Iowa and tell the truth. It is a boondoggle.

Diverting corn production to subsidized ethanol raises food prices across the globe, uses more energy than it saves, and reduces fuel efficiency. Bjorn Lomberg makes the case. Even Al Gore agrees .

If she made that case and lost the Iowa caucuses, the electorate would recognize that she lost because she told the truth. It would diminish the impact of losing and make the winners look bought.

Just my thoughts.
