UPDATE
Two weeks left. Obama's probability of winning is up 1.6 from a week ago to 67.6%. Although most say that he narrowly "won" the second debate, he not receive nearly the same bounce as Romney the week before.
The electoral forecast is 288 Obama, 250 Romney, an Obama -1 from last week.
The only change in the swing states is North Carolina is now likely Romney. Pennsylvania has suddenly been added as the tenth swing state, and debuts as likely Obama.

Lastly, whomever "wins" tonight's debate will likely again be whomever has waxed so cold at telling lies that it is better presented as his second nature. See this fact-check analysis of the second debate from the Annenberg Public Policy Center:
