Kevin Drum: "As practically everyone except politicians pandering their way through Iowa knows, corn ethanol is a boondoggle. It doesn't do much to reduce oil use, it doesn't do much for the environment, and it doesn't do much for your food bill. All it does is make corn farmers happy." Indeed. In a lot of ways, the most impressive thing about Bill Richardson's energy speech is that he managed to get through the whole thing without mentioning ethanol.
