Thursday the Senate voted 41-58 against a motion to suspend the rules and accept an amendment offered by Sen. Chuck Grassley, (R., Iowa), to enact a retroactive extension of the biodiesel tax credit. The motion needed 67 votes to pass and was needed because Senate Majority Leader Harry Reid, (D., Nev.), had filed an amendment tree preventing additional amendments from being filed. - Source
