Why would anyone want to convert a vehicle to run on E85 fuel and reduce their fuel mileage significantly?

GM is touting the number of new vehicles designed to run on E85 fuel, but the company does not talk about the reduced mileage.
Actually it isnt that big of a mpg drop, and if its sold cheaper like $2 vs $3.30 then it doesnt really matter. That and what shadams said is true if you have a high compression ratio
