On his electoral map on Rove.com, Karl Rove turns Ohio blue. Rove, to Chris Wallace on 'Fox News Sunday': 'In order for McCain to win, he's got a very steep hill to climb. He's got to win all of the toss-up states ... Then he needs to strip away Ohio and Indiana ... And then he needs to either win Colorado and Virginia ... or win one of them plus Pennsylvania ... It's a steep uphill climb.'
