Live odds: 10:24

Here are McCain and Obama's chances (according to Intrade's state-by-state numbers) of getting various minimum numbers of electoral votes as of 10:24 pm. Very likely Obama will make it over 350 electoral votes, still about a 1 in 4 chance of getting 375+.

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.
