McCain spokesman, quoted by Josh Marshall:

"Obama is running out of states if you follow out a traditional model. Today, he expanded his buy into North Dakota, Georgia and Arizona in an attempt to widen the playing field and find his 270 Electoral Votes. This is a very tall order and trying to expand into new states in the final hours shows he doesn't have the votes to win."

Marshall notes: "Translation: The fact that Arizona has moved into the toss-up column is a devastating development for Obama."
