Zogby's latest says Obama-Biden 45%, McCain-Palin 47% I haven't seen any other new poll numbers yet, but expect there will be more out this weekend. Gallop releases their numbers every few days now and should have new ones out soon.
Rasmussen and Gallup Rasmussen Tracking poll shows Obama 47, McCain 43 Gallup Tracking Poll shows Obama 49, McCain 41 I don't know much about polls, but would trust these numbers more than Zogby's because these are more consistent with the traditional convention bounce.
The first thing that caught my eye about the Zogby poll is that it is an online, interactive poll. Usually, I think of online polls as representing a self-selected sample, and therefore totally worthless. Apparently their methodology makes the sample more representative than the typical online poll, so I don't know. Looking at their history, I think Zogby is often out of step with other polls - sometimes they turn out to have been right, and sometimes way off. I'm thinking especially of '04, when they showed Kerry trouncing Bush. One point in favor of online polls is that they should get some of the demographics that only have cell phones and are missed by the usual telephone polls. On the other hand, they will miss those that don't have computers, or are not comfortable with the internet. Intuitively, that should skew towards Obama supporters. Maybe it does, and Zogby overcorrected for that? Real Clear Politics keeps a running average of polls. They're showing Obama ahead by 3.9 points for the period from 8/19 through 8/29, so that doesn't reflect the Palin selection.
