CNN's Battleground States map shows NC with 92% of precincts reporting and McCain ahead by only 2702 votes, out of a total of 3.9 million votes [shortly after 10:00pm CST].
Oh, and 2 other notes, neither of which is likely to be useful --
Florida is 51% Obama, 49% McCain, or about 160,000 votes ahead, with 86% of precincts reporting. NB, later-reporting precincts here tend to be in the red parts of the state.
CNN appears to have called Ohio for Obama, a flip from red to blue for the Buckeye State if true. I can't remember the site where I saw the information, but whoever has won Ohio in the past 10Presidential elections has won the whole kit and caboodle. But probably it's safer to rely on your magic 8-ball for prognostication.
