The Associated Press reports that “ethanol production has become a key issue in Iowa’s closely matched U.S. Senate race, with both candidates pledging support for an industry that is important to the state’s corn-powered agricultural economy.”  

“Democrat Bruce Braley and Republican Joni Ernst have both sought to assure voters that they oppose a proposal from the Environmental Protection Agency that would reduce the amount of ethanol and other biofuels that must be blended into gasoline.”  

“Braley is touting his efforts as a congressman to halt the changes, including testifying against the cut at an EPA hearing. Ernst also argues that she supports maintaining the existing standard — known as the Renewable Fuel Standard or RFS — though she has taken questions over statements that she is opposed to subsidies from a ‘philosophical standpoint.’”  

“Recent endorsements in the race show that both candidates are getting some support from farming groups. The Iowa Farm Bureau’s political committee endorsed the farm-raised Ernst, while the Iowa Corn Growers Association PAC backed Braley. Both groups cite the RFS as a key issue for members.”
