This has got to be just killing a lot of Wisconsin Republicans. I'm pretty sure that if you live in Wisconsin, you're automatically a Green Bay Packer fan. You can't not root for the Packers to win, or else you get sent to Illinois to live in exile.
Here's the scoop (straight from Snopes.com):
A recent item of this ilk maintains that the results of the last game played at home by the NFL's Washington Redskins (a football team based in the national capital, Washington, D.C.) before the U.S. presidential elections has accurately foretold the winner of the last fifteen of those political contests, going back to 1944. If the Redskins win their last home game before the election, the party that occupies the White House continues to hold it; if the Redskins lose that last home game, the challenging party's candidate unseats the incumbent president. While we don't presume there is anything more than a random correlation between these factors, it is the case that the pattern has held true even longer than claimed, stretching back over seventeen presidential elections since 1936.
The Redskins play the Green Bay Packers on Sunday, October 31. Who are you rooting for?
