I have cosponsored a bill to remove that tax, which was initially intended to protect US sugar producers, but is now interfering with energy policy. Plus, ethanol has downsides. In addition to the fact that it results in more emissions than gasoline, it is corrosive and cannot be used at too high a… Read More
