Not having done much research on this, I would tend to agree that McCain is on the right side of this issue--and Obama is not.

But the salient question is how significant this issue is against others. For my money, it's nothing compared to the Iraq war.

And there's no question who's on the wrong side there:   McCain.

I cannot imagine anybody basing a vote in the fall on how Obama and McCain view ethanol. Sounds like a parody of a one-issue voter.
