A group backing biofuels is telling 2016 candidates coming to Iowa to quit picking oil as the winner in energy policy. America’s Renewable Future (ARF) has taken out radio advertisements and full-page ad in the Des Moines Register, Dubuque Telegraph Herald, and Sioux City Journal warning candidates that oil in U.S. energy policy is a government-subsidized stranglehold supporting foreign oil.

In addition, the political group has deployed a petition urging caucus-goers to “tell candidates to stop supporting hundred-year-old, big government subsidies for the oil industry, and to level the playing field by supporting the RFS. To boost this effort, ARF’s radio ad will run Tuesday through Thursday of this week. The aggressive radio buy includes spots on WHO Radio in Des Moines, WMT in Cedar Rapids/Iowa City, and KSUX in Sioux City, among other stations across the state.

“Some politicians campaigning in our state are not listening to Americans who want a cleaner, more secure U.S. energy policy, and a renewable choice at the pump. We are calling on Iowans to sign our petition atwww.AmericasRenewableFuture.com telling Washington politicians to stop picking Big Oil over homegrown renewable fuel,” said ARF co-chair, Bill Couser, “Our call will be sound across the state via radio and online, urging Iowans to let candidates know where they stand.”
