Huckabee is asked about ethanol, whether the free market should determine whether they are used. Huckabee says it's critical for national security and economic interests to use "biofuels." It's a tremendous boondoggle, in fact, and Huck, a pinko through and through, is pandering. Blathers about "Islamofascism," as if ethanol gives us independence from the Arab world! "We can't wait till another generation." I hate Huckabee.
The reality is that ethanol benefits two groups: the politically powerful corn farmers who grow the now premium priced corn, and the oil industry because now they can sell less efficient gasoline for a higher price. Oh, no one mentioned that 100% petro fuel is both cheaper and more efficient than ethanol. Or the fact that this means that when you buy gasoline with ethanol additives - you are buying more gas more often for a higher price than if the additive wasn't there. Well, now you know.
Corn-based ethanol subsidies disadvantages a lot of folks though: food manufacturers (veggies, beef, chicken, and other protein), sugar producers, and normal folks who get to pay higher prices for well - just about everything.
