I saw the debate as an uneven draw. The economic issues inflicted damage on McCain, who was clearly unprepared, but the shift to foreign policy meant that McCain improved his position as the debate wore on.
Other points
--No serious gaffes, although there was a lot of BS
--Obama was well briefed and held his own for the most part
--McCain explained the earmarks issue in the best manner I have ever seen presented, although I don't think he should have harped on it.
--Obama lied when he denied voting to raise taxes on those making more than $42,000
--McCain failed to call out Obama for his BS enough
--Obama failed to BS his way through the Iran meetings and nuclear power
--Linking Obama to Bush in terms of stubborness was one of McCain's best lines.
--Obama: "No American soldier ever dies in vain" WTF? What did you think would happen if we abandoned the Iraqis?
--McCain's closing was strong
--I doubt this will change the state of the race by a significant margin
