Great article here:

People may say what is politically correct, the questions may be leading, the pollsters may be biased. A pollster can still bill for an inaccurate poll. Bookmakers must make an accurate line or they lose -- period."
"Gamblers have more experience with cheaters... they take voter fraud into their metrics. Polls don't. Nor do polls take into account how each state's secretary of state factors in, or systems within a state designed to eliminate voters; Jimmy the Greek called these 'the intangibles.'"
Michael Robb, political expert for the British bookmaking site Betfair.com, lets the record speak for itself: Halfway through Election Day in 2004, when a CNN poll showed Kerry taking the lead, Betfair had Bush with a 91% chance to win.
Betfair also had all 50 states right in 2004. As did rival site Intrade. Koleman Strumpf, a University of Kansas economics professor who tracks betting trends, believes wagering is an incomparable barometer of an election. Among the reasons he gave:
"Relative to the polls, the betting markets have to think hard about what they're saying since they are putting their money at stake. Also polls tend to reflect what people are thinking at a given moment, versus a forecast of what will happen on election day -- post-convention bounces, for instance."

CURRENTLY ON BETFAIR AND INTRADE, the two sites are UNANIMOUS again: Obama takes FL, NC, VA, PA, OH, CO, and NV; he loses IN, GA, and MO (actually Betfair has MO as a wash, but close enough)
Betters' current prediction: Obama 353 to McCain 185
*Intrade's homepage currently has its electoral predictor on the front page, being updated in REAL TIME based on current betting stats. Check it out, it's very cool.
