Sour grapes on Brandstand’s part (especially because he and his family are addicted to Ethanol).
Ben Carson lost maybe 1% (at most).

And the governor of a state is pretty close to activity in his state.
If I were running for governor in that state, I’d note that a suspected 28% of Iowans favored reducing ethanol tax subsidies. That means 72% do NOT favor it. He had not reason at all to think anything about ethanol tax subsidies.
