Texas Sen. Ted Cruz, who leads in the polls ahead of the Republican presidential caucuses in Iowa on Feb. 1, “told folks at town-hall meetings in northwest Iowa that he supports phasing out the Renewable Fuels Standard through 2022,” reports DTN. Previously, he opposed subsidies and mandates. Said DTN, “A big lingering question is: What does Sen. Cruz mean by a five-year phase out? The RFS from 2017 to 2022 is not supposed to ‘phase out,’ but climb. This is what caused the entire controversy when EPA dialed back on the mandated blend volumes for 2014-16. Under the law, total RFS biofuel blends are supposed to hit 24 billion gallons in 2017 and continue growing to 36 billion gallons by 2022.”
