As usual, the real story is buried in the fourth paragraph (always the fourth paragraph). Kerry's handlers have apparently told him he has to defend Michigan by spending time there...that tells you everything you need to know about how badly their campaign is going. Michigan should have been a slam-dunk for Lurch.
As for the rest of the story, it's possible to be too wealthy when running for office...people continually question whether you're really serious or not (Perot, Trump, et al).
