The Keystone State... Called for Obama

John McCain's plan to win tonight? Swipe Pennsylvania.

Alas, it was not to be. At 8:00 on the dot--the moment the polls closed--the networks called the Keystone State for Obama.

Without it, McCain now needs to win Ohio, Florida, Virginia and Indiana. If he loses any one of those states, his path to 270 becomes prohibitively steep. If he wins them, he still needs to hold onto the Western states of Colorado, New Mexico, Iowa and Nevada, where Obama has been polling much better than in the east.
