All republicans are supposed to be for limited government regulation and for market driven solutions. Does anyone else find it troubling that the ethanol program that is government regulated and supported by tax dollars is supported by all conservatives except Cruz. I was not really a Cruz fan until this issue came up and he had the courage to say he would eliminate the program. That cost him a great numberl of Iowa votes at a time he was ahead of Trump. Rubio folded like a cheap lawn chair.
