This really jumped out at me - MSNBC's breaking item on "major obstacles" to voting just happens to mention exactly the states that Fivethirtyeight's Nate Silver pinpoints as likely to decide the election.

From nbc:

[http://firstread.msnbc.msn.com/archive/2008/11/04/1634499.aspx]

VIRGINIA: Dozens of polling places are experiencing varying degrees of machine malfunctions..
PENNSYLVANIA: Voting machine malfunctions are widespread and at least a dozen locations..
And problems in "Several other states like Florida, Ohio, Colorado and Michigan"

And, from Nate Silver's election night viewers guide:

"Virginia, for my money, is the most important state in this election. If John McCain loses it, his path to victory is exceptionally narrow--he would need to pull out an upset in Pennsylvania, while holding on to Florida and Ohio, and avoiding a sweep out West."

What an amazing coincidence...
