The Democrat EPA of today wouldn’t dare give up the Ethanol regulations for fear it would be noticed there would be no change in atmospheric pollution, thus no reinstatement of the law upon arrival of better times, thus one less major contributing entity to the Democrat coffers.
If we discovered the ideal fuel today: cheap, non-polluting and plentiful, the Democrats would regulate and tax it out of existence. The EPA is not in business to save the environment, it is to make us slaves to the progressives.
