What do you mean wager on it?
www.intrade.com is a gambling website.
Pollsters who, if they're wrong, you can take their money. The only group out there with REAL motive to get it right. We all know that CNN, FOX, and MSN benefit tremendoucly from a nailbiter. They lose millions of $ in ad revenue if the election is a blowout.
If Intrade bullshits, people buy wagers on it, and clean their clock.
