The Redskins are favored by 2 points, but it's the straight-up winner that matters every four years.
For 17 of the last 18 Presidential elections, when the Redskins win their final home game before the election, the incumbent party's candidate also wins; when the Redskins lose their final home game, the challenging party's candidate unseats the incumbent party's candidate.
Obama is favored to win by 104 to 128 electoral votes; just wait until the game's outcome before making your final bet.
Of course, the first time that this didn't hold was 2004, so we're either at the start of a new coincidence or that was just a (very close) bump in the road.
Knowing this predictor, who do you want to win the game?
