An earlier posteron another thread indicated that Internet betting (including Intrade) is now illegal in the United States, so that most bettors are Brits or other foreign national not always well-versed in American politics, FWIW.
And I posted that it’s probably not true. The rumor is going around because InTrade doesn’t accept credit cards.
And, anyways, that would have a tendency to add credibility to the market as one step removed from the emotionalism that americans attach to politics. Guys who do well betting on football teams do better than guys who put money down for their own team.
I’d love to find some other unbiased indicator, especially one that we can point to for debates. Most of the debate threads are all Mr. Superduper’s follower pointing out how super he did versus Mr. Whooptedo’s follower pointing out what a big splash he made. No real objectivity.
