MSNBC and ABC have called Pennsylvania. No CNN yet. But if Chuck Todd says it (he's with MSNBC), one tends to believe it. Pretty big news, obviously.
Re Virginia: Remember that Norfolk-Virginia Beach-Hampton Roads haven't come in yet. Neither has northern Virginia. Those are Democratic strongholds. So Virginia will tighten considerably.
Re Florida...surprising Obama margin so far. And historically, south Florida (Dem) reports later.
If you're watching CNN you're noticing John King go over all those red counties that Bush carried by 12 or 15 or 18 points and McCain is winning by only six or nine, you're seeing exactly why the Obama field game is strong. They knew coming into this exactly how many votes they needed in every precinct in a state like Indiana to improve on 2004 and hold McCain's gains to a minimum so they could make up the difference in the blue areas. I didn't pick him to win Indiana but from what I'm seeing up to now I think he's in a decent position to pick it off.
