Corn and Iowa are one and the same. Iowa has the first caucus of the presidential primary season. Politicians of all stripes tend to like corn. (Whether they want to or not.)
Democrats still seem to think they can revive their brand in farm country by pledging allegiance to the government’s long-standing efforts to prop up ethanol. Iowa is America’s top ethanol producer, with 44 plants that help support more than 40,000 jobs, and so far none of the Democrats competing there have broken the faith.
