This article seems pretty light on evidence. Where is the data comparing election outcomes to both polls and betting odds over time? The argument seems to be based mainly on this: > Political betting sites won’t give one presidential candidate great odds of winning just to influence voter perception. They’d stand to lose serious money in such an event. Of course, political pollsters also stand to lose money if their polls are wrong, because if they have a bad enough track record they will no longer have customers. When the polls are wrong it really pisses off the pollsters' two main customers: political campaigns who want to know how popular their candidate really is, and the news media which wants their election predictions to be correct.
