re: "Mitt Romney claims that he's a middle-class American"
Isn't that the claim YOU make, too?
The average U.S. *HOUSEHOLD* makes about $50,000.
I suspect you misunderstood Mitt Romney's claim. He probably meant that he's an average guy - in terms of his values and friends, or perhaps that he had a "middle class" upbringing. I seriously doubt he ever said that he is currently "middle class" in terms of income, but I don't know. I don't follow Romney very closely... or support his candidacy, for that matter.
But I'm curious since what you've posted *IS* pretty bizarre. Can you show me your source?
