Senator Jeff Bingaman (D-NM) confirmed he is backing a Senate compromise on ethanol subsidies struck last week between ethanol critic Sen. Dianne Feinstein (D-CA) and biofuel backers Sen. John Thune (RSD) and Sen. Amy Klobuchar (D-MN). Senator Feinstein says a formal bill is being drafted that the Senators hope will be part of a larger debt deal.
