Similar 83-point advantages among their own party, Kerry up 3 points among registered independents, yet Bush up by 1 point overall = Gallup sampled 2% more registered Republicans than Democrats. That implies that Bush's 7-point lead among likely voters is actually smaller than that, more like 4 points. Good news, but not as good as it might seem at first blush.
Among likely voters (internals not available), Bush has the seven point lead. The breakdowns in that group will be much more favorable for him.
