Oh, and probably most of the rest of the field is the new attention paid to Huckabee. At Intrade, Thompson is now within 1/2 a point of McCAin & Ron Paul, with Huckabee less than a point behind them.
Some previous market predictions. Sample from many.

No longer is Thompson within a 1/2 point of Ron Paul. Ron Paul has passed Thompson, and is nearly a point ahead!
