This is more accurate than a POLL because it is a MARKET. Markets have better predictive records than polls. Another good one with a great track record is the Iowa Electronic Market http://www.biz.uiowa.edu/iem/ where people can bet real money on several races, including President - Winner Take All and President - Vote Share.

I am not a fan of the Iowa Markets. they had Kerry up until Mid October in 2004, and then had the GOP keeping the Senate in 2006 all the way until Nov 1.

Use to follow but not a good predictor.

However, still less than perfect which means that McCain and VP-candidate Romney still have work to do. ;-)
