Republicans split on ethanol share in national fuel mix

The House passed legislation to allow year-round sales of E15 fuel (gasoline blended with 15% ethanol), but Senate Republicans are divided on the issue. Supporters from corn-producing states like South Dakota's John Thune back the measure as a way to lower gas prices, while opponents from oil and refinery states like Wyoming's John Barrasso oppose it. The bill would likely need to be attached to must-pass legislation to advance in the Senate.
