The topic of ethanol came up in last week’s GOP debate in Miami, although it is unlikely to play a big role in the Florida primary this week.

During the debate, Sen. Ted Cruz (R-TX) boasted that he campaigned against ethanol in Iowa because he wants to cut the size of government programs. “When I went to Iowa and campaigned against ethanol mandates, everyone said that was political suicide,” said Cruz. “If we’re going to stop bankrupting our kids and grandkids you’ve got to be willing to take on the lobbyists…specifying these are the programs I will eliminate.”

Donald Trump responded that Cruz did a flip flop on ethanol in Iowa. “Ted did change his view and his stance on ethanol quite a bit at the end,” said Trump. “He did change his view in the hopes of doing well.”

Cruz outlined his stand regarding ethanol and the Renewable Fuel Standard in a January 6 Des Moines Register editorial. He does advocate a “phase out the Renewable Fuel Standard” but at the same time Cruz says he will “vigorously enforce our antitrust laws to ensure that the oil-and-gas industry cannot block access to the market for ethanol producers.”
