We last examined the Intrade market on the 2012 Republican nomination shortly before the two mid-November debates. In today's update, we'll see how the debates have altered the Intrade market's perception of the race.
As far as the frontrunner is concerned, the debates had no impact. Mitt Romney dominated the field before, and his numbers are unchanged. Romney stands atop the field at 69.6%. By contrast, the lesser candidates have been shuffled. The big change is that Rick Perry, who has been on a decline since he first participated in a debate in September, has finally been ground into dust. Before the debates, he stood at 40%. After the September debates, he dropped to 20%. He slid down to 10% as it became clear he would not recover in October. Now, after Perry's gaffe at the November 9th debate, he has lost nearly all of his support. Perry is currently trading at 3.7%.
Newt Gingrich rose at Perry's expense. He now stands at 14.3%. Just a month ago, he was in the low single-digits; now he's in second place, albeit a very distant second. Herman Cain has slid to 4.0%. That's not much of a drop considering the sexual harassment scandal, but Intrade has always been very skeptical of unconventional candidates like Cain. Still, it's interesting to see that Perry is now behind both Gingrich and Cain. Also in the mire of the three percent range are Ron Paul and Jon Huntsman, at 3.2% and 3.1%. Michele Bachmann has long since been pronounced dead, and she trades at 1.0%. Rick Santorum--who may be okay on paper--is nowhere in the polls, so he is at 0.4%.
The Iowa Caucus market has changed more dramatically. While Romney is still at about 40%, Gingrich is now in second at 21%. Cain has fallen to 15.2%, and Perry is at 7.5%. This reflects the fact that the Intrade market believes someone has to have a chance of beating Romney in Iowa. If it's not Cain or Perry anymore, and if it's not Bachmann or Santorum, that leaves Gingrich. This is despite the fact that Gingrich has not done well in Iowa polls (aside from an outlier or two).
The New Hampshire market still says Romney has it in the bag. South Carolina has behaved like Iowa, with Gingrich picking up Cain and Perry's slack. The Florida Intrade market is still traded too little to be efficient, but Romney has catapulted to 65% there. The Nevada market looks like the New Hampshire one, with Romney dominating.
