In Iowa, ethanol trumps even healthcare

Iowa Gov. Kim Reynolds, a Republican, is coming to Washington, D.C. Tuesday to make the case for ethanol in planned meetings with Vice President Mike Pence and EPA Administrator Scott Pruitt.

Driving the news: She'll be defending a federal mandate that requires refineries to blend biofuels — mostly corn ethanol — into the nation's gasoline supply. Corn-rich Iowa is the nation's top biofuels producer, and also a pivotal political battleground.
