If there are still nervous Obama supporters out there, Sam Wang at Princeton has the perfect tonic.

His bias analysis enable you to discount whatever worries you may have — Bradley effect, impact of voter suppression, whatever — into an electoral vote calculation. So if you believe the latest polls are completely accurate, Wang’s calculation is that Obama will end up with 352 electoral votes. If your a complete worrier, and you think the polls are overstating Obama’s lead by 5 per cent, then he’ll end up with 278 — still enough to win.

There is a lot more interesting statistical stuff at Wang’s site.
