DES MOINES, IA - The field of Republican hopefuls has changed again.
First Mitt Romney had won Iowa. Then Rick Santorum pulled ahead in a recount. But now a second recount has determined that William F. Cobb, an ear of corn, is the official winner of the state. The home-grown candidate has been the leader of a grassroots movement starchly opposed to the production of alternative fuels, particularly ethanol.
