December marks the tenth anniversary of the passage of the Energy Independence and Security Act (EISA), and its wildly expansive Renewable Fuel Standard (RFS), better known as the ethanol mandate.

President Trump recently paid homage to the RFS, as all feel they must do to play politics in Iowa. Too bad. Trump, who claims he wants to “drain the swamp,” will never manage it, if he fails to see that the swamp is full of ethanol.
