Monday night's odds

Below are McCain and Obama's chances (according to Intrade's state-by-state numbers) of getting various minimum numbers of electoral votes for Mon. Nov. 3, on the eve of the election. McCain's chances of winning have dropped to 0.39%, according to the Intrade state-by-state numbers. The McCain-to-win front-page contract gives him a 9.8% chance to win.

As always, each candidate needs at least 270 electoral votes to win outright, and a tie at 269 that throws it into the House isn't impossible.

Matt,

Great site! Do you have the individual state numbers from Monday night, and would you be willing to send them to me?

I'm looking to do a follow-up post to my blog post here:
http://blog.mercury-rac.com/2008/01/25/how-to-interpret-prediction-market-results-on-elections/
but I need the Monday night InTrade data. I plan on comparing how accurate it was and how accurate the final percentages from fivethirtyeight.com were in the end.

I'm more than happy to chat if you're curious, and I'd be more than willing to cite you in the post I'm writing!

Best regards,
Jed
