Monday Morning's Odds

Here are McCain and Obama's chances (according to Intrade's state-by-state numbers) of getting various minimum numbers of electoral votes for the morning of Mon. Nov. 3, the last day before the election. Apparently traders on Intrade have become significantly more confident in Obama's chances since yesterday -- his national Obama-to-win contract is above 90% for the first time I can think of, and my state-by-state simulations give McCain about a 0.5% chance to win.

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.
