From Ambinder:

I've checked in with the boiler rooms in both campaigns; they're doing they're own very sophisticated exit polls... Here's what I'm hearing: FL -- both sides say they're hitting their turnout goals...Obama may be exceeding his... in North Carolina, Republicans concede that Democratic turnout appears very high.... the same goes for Virginia.... in Pennsylvania, Democrats are confident that they're meeting their goals...Republicans are waiting for data.

Remember, Obama's state turnout targets are generally thought to be higher than McCain's....
