The Washington Redskins are playing this Sunday, and
the outcome of Redskins home football games has correctly predicted the winner of every U.S. presidential election since 1936, that's the past 17 elections.
Their last game before the election is sunday. If thy win, then this predictor says that Bush will win. If they lose, this says Kerry will win it.
