I mostly jest with my headline, since there's no way to really make something like that "official". But Obama has now pulled into a two-point lead in the influential Gallup tracking poll, the first time he has been ahead of McCain since the RNC:
Yes, it's only a two-point lead, but this is a more dramatic move than it may initially appear. The Gallup daily tracker uses a three-day rolling average, so a delta of 3 points in one day is a pretty significant shift.
Of course, it only matters if Obama can keep it going.
