It's called politics. He has to beat the Republican competition to advance to the finals. If your complaint is about principles, you should be directing it at those who benefit from ethanol production, the Iowan farmers. You can stand on principle all you want, but the pragmatic Politian will weigh principles against vices. Ethanol may be a dumb environmental idea, but it fits the Trump message made in America by people who work. My take, he wants to win Iowa and doesn't care a rat's ass about ethanol.
“You can stand on principle all you want, but the pragmatic Politian will weigh principles against vices”
In other words, just the same old politician who will say anything to get elected and then do what he wants. Sounds a whole lot like the scondrels that we have running the GOP now. Guess principles don’t matter after all. Thank you for telling us where you, and Trump stand.
