Clearly Mittens misspoke because he made a factual error. It was not just an ideological perspective. Obviously, millions of folks who don't pay income taxes will be voting for Mittens. Heck the correlation between wealth and partisan affiliation is a weak as it has ever been in the Fruited Plain - certainly in my lifetime at least, and my parents' lifetime as well. Thank you.
A factual error? So, in non-lawyer speak, you're claiming he was lying? Or do you think he was so misinformed to believe something that, as you point out, is wildly off target.
