During Wednesday night’s CNBC Republican presidential candidates debate, Dr. Ben Carson was asked about a comment he made to the Des Moines Register earlier this year that he would “probably be in favor” of using oil subsidies to increase pumps for ethanol blends.

The question posed by the CNBC moderator was “Isn’t that just swapping one subsidy for another?”

Carson responded by saying he was “wrong about taking the oil subsidies” and that “the best policy is to get rid of all government subsidies and get the government out of our lives.”

“All this too big to fail stuff and picking winners or losers, this is a bunch of crap,” said Carson.

Carson said nothing about ethanol in his answer but America’s Renewable Future State Director, Eric Branstad issued a statement to clarify that ethanol does not receive government subsidies, “while the oil industry does and has for the past 102 years.”

“Iowans want a candidate who will take the time to learn about the issue, not just repeat the oil industry’s talking points,” said Branstad. “We hope that next time he comes to Iowa, Dr. Carson will actually meet with farmers so he can get a better understanding of the full issue and that he will choose to side with Iowa farmers instead of Big Oil.”
