yeah, i know im stating the obvious. but the networks never emphasised that point enough. i assume it was because the exit poll for pa was just dead wrong.
The early vote count was really skewed towards Philadelphia. Kerry had like a 20% lead with 1/2 the precinct counted, which must mean that Bush carried the other 1/2 by around 16%. So you had two halfs with about a 36% difference (or about the difference between Rhode Island and South Carolina).
By contrast, the margin in Texas was pegged with about 20% of the vote in, and did not move by even 1% as the rest of the votes came in.
