Cedar Rapids Gazette: Sen. Chuck Grassley, R-Iowa, is frustrated that the debate over ethanol and biodiesel is characterized as an “Iowa discussion” when other states also have a stake in the federal policy. “How come this whole thing, discussion with the White House and the EPA and everybody else, just seems to be an Iowa discussion when there’s at least 14 states that are big corn-growing states, and every one of those states, I’ll bet, has ethanol in it,” Grassley said during his weekly conference call with reporters. “Where are the senators from all of these other states?”
