This is a good, short video from Reason TV discussing the utter boondoggle of ethanol. It is not a viable alternative to gas. It is driving the cost of food prices through the roof. It is hurting the environment and takes nearly as much energy to produce as it produces in energy when mixed with gasoline. In short, it is hurting America and the world.
That said, the opening scene is a real cheap shot of John McCain of the type I would expect from the NYT. They use old video of him when he supported the idea of ethanol. He long ago changed his position on ethanol, voting against the Farm Bill discussed in the video above and telling the people of Iowa that ethanol subsidies had to end. Mandates need to also.
