I'm sure you know that virtually all ethanol added to fuel is made from corn regardless where you buy it. Same in IL and WI as it is in MN, yet, IL and WI both have huge gas taxes while MN apparently does not. We're all using the same kind of gas with similar ethanol ratios... The amount can vary, but most places I've seen have the same 10% minimum label on the pumps. Emissions data that I've seen comparing fuel with and without ethanol has been fairly inconclusive. The real problems with emissions are older, improperly maintained vehicles more than the type of gas they're using. And, yes, traffic congestion as you mentioned doesn't help at all, either.
Personally, I think they're keeping ethanol around because it helps cut down on the amount of petroleum needed to make gasoline, so we don't need to buy as much from OPEC. Also, as sort of a bonus, the ethanol production is bringing money to the farmers that supply the corn, which I'm all for. Half of my family are/were small-time farmers, but it's very hard to scrape by these days unless you're running a fairly big operation. I think the improved emissions claims are being thrown out there to keep the hippies and other Ralph Nader supporters happy.
