Democrats preparing to move oil subsidides to biofuels?

Already, ethanol is an incredibly subsidized product, as is the corn from which most ethanol is derived. Yet, the profit margins for ethanol producers are actually greater than oil profit margins. For many, this isn't a problem because of the belief than ethanol is more green than petroleum, or that ethanol helps reduce foreign oil dependency. Many Democrats in Congress also have the same belief and those Democrats are preparing to roll back tax subsidies for oil companies and use them for biofuels according to the Detroit News.
