Last Tracking Poll of the Day

So another day of tracking poll reports comes to its happy conclusions. I previously reported here the results of Rasmussen and Research 2000. And my compatriot atdnext also provided a summary of Diageo Hotline here. Now Gallup Daily is out and suggests that the distance between Senators Obama and McCain is two points wider today than it was yesterday:

Obama 49%
McCain 42%

The results yesterday were 48-43.

So to sum up:

Research 2000/Daily Kos: Holding steady 51-40, though the number masks Obama's strongest day yet in yesterday's contribution to the three day roll.

Rasmussen: Numbers steady all week long and exactly the same as yesterday.

Diageo Hotline: Obama up one point over yesterday.

Gallup Daily: Obama up two points over yesterday.

Talking Points Memo observed about today's trackers:

Adding these polls together and weighting them by sample sizes, Obama is ahead 49.9%-42.5%, even wider than his lead yesterday of 49.4%-42.9%.

TPM's weighted lead yesterday was 6.5 points and today, 7.4 points.
