Huh?
Ethanol has a far lower energy content that gasoline. Ethanol creates more smog than using regular gas, and the EPA's own attorneys had to admit that fact in front of the justices presiding over the Third Circuit Court of Appeals in 1995 (API v. EPA).
All fuels laced with ethanol reduce the vehicle's fuel efficiency, and the E85 blend drops gas mileage between 30% and 40%, depending on whether you use the EPA's fuel mileage standards (fueleconomy.gov) or those of the Dept. of Energy.
If Ethanol had been pitched not by Progressives but America's own oil industry, they'd be accused of attempting to ???water down??? American's fuel to rip off consumers. Ralph Nader would be filing class action lawsuits on behalf of all consumers for the losses in lower mileage and damage to automobile engines, and Al Gore would go on a rampage about the increased net carbon footprint and other environmental damage because of the resource intensive nature of producing Ethanol.
