Conventional political wisdom has held that given Iowa’s importance in US presidential contests as host of the first-in-the-nation nominating caucuses, the Renewable Fuel Standard is pretty much unassailable.
The federal biofuels mandate enjoys immense bipartisan support in the state, where corn is king.
Candidates hoping to curry favor with state voters would need to wholeheartedly endorse the RFS or at least pay lip service to the law while campaigning there. Iowa, after all, leads the nation in biofuels production, with 41 ethanol plants in the state, along with 18 biodiesel facilities.
But, if RFS opponents are to be believed, the political landscape could be changing.
