USA Today has a sharp editorial about ethanol:
The law, an expansion of a mandate adopted two years earlier, called for impossibly large quantities of corn to go into fuel production rather than onto people's tables, driving up food prices. This year, the mandate requires 16.6 billion gallons of ethanol, absurdly consuming 37% of the nation's corn crop and requiring farm land roughly equal to the size of Kentucky. ...Why would Congress fleece consumers in this way? There's only one reason: to please a well-organized farm lobby, which collects most of the money consumers are forced to waste.
