McCain had a 50-45 night last night, but O’s lead jumped 2 for some reason due to the vagaries of tracking poll math/rounding issues.

How do you know it was 50-45?

Say what? Only way McCain can have a 50-45 night and lose ground is if Rasmussen changes weighting.

Did you mean that Obama had a 50-45 day yesterday?

It might actually be better than 50-45 for last night, but the number is certainly reasonable. I hesitate to put McCain’s number much under 45 given the real lack of “internal” movement. Anyway, I can say, without a doubt, that Obama’s number in the one-day sample today couldn’t have been higher than 50.25%.

The true “internal” number for the three-day sample is a margin of O+5.06% (with rounding it appears to be 6). Yesterday, it was O+4.55% (with rounded it appeared to be 4).

Another pro-McCain sample (in comparison to the three-day number) falls off tomorrow. Friday, a pro-Obama sample falls off.

I think that’s about it.
