Deeper into the addiction I go...
Today
The two tracking polls for Saturday have been released. Gallup shows Obama 47%-45% McCain, down from Obama 48%--44% McCain the day before. Rasmussen shows Obama 49%--46% McCain, which is actually an increase of 1% for Obama from yesterday's 48%--46%. The Diageo tracking poll, which yesterday showed Obama ahead 46%-40%, is not released on Saturdays and Sunday.
Last Two Days
Day by day experts Haggi and Nate Silver concur on the Thursday and Friday results for Gallup. Both estimate that Obama was up by 1% in Thursday's polling, but that McCain was up by 2% in Friday's polling (see Haggai's and Nate's numbers). However, they disagree strongly on the two most recent days of Rasmussen polling. For that poll, Nate estimates that Obama was up 2% on Thursday and 1% on Friday, while Haggi estimates that Thursday was a tie but Friday showed Obama up by 6%.
Tomorrow
Haggai and Nate seem to agree that McCain holds a 0.5% lead in tomorrow's Gallup poll, with today's surveys still pending. So, for Gallup, we can safely assume that if tomorrow's tracking poll is tied or shows an Obama lead, then today's Gallup polling will have been pretty good for Obama. However, if McCain leads, then his convention bounce has not yet begun to fade.
While we do know that Obama leads in Rasmussen's Sunday poll, pending today's surveys, we don't really know how much he leads by. Nate estimates about 1.5%, while Haggai estimates 3.0-3.5%. It is a pretty big discrepancy. Obama should go down by about 2% tomorrow if Nate is correct, while he should hold about even if Haggai is correct. I guess we will have to wait and see.
Analysis
It is starting to look like this entire two-week stretch didn't change much in the campaign. The above analysis seems to indicate that Obama leads by about 1.3-1.5% 0.5%-1.5% in the combined Gallup and Rasmussen tracking polls for the two nights following Palin's and McCain's speeches. This is, I believe, exactly where the campaign was before Obama choose Biden. So, after the initial Biden dip, the big Clinton bounce, the decent Obama speech, the small Palin announcement drop, the huge Palin post-selection "vetting" bump, and the McCain-Palin acceptance speech fall, we end up right back a the same narrow Obama lead where we began.
Personally, I am hoping that the tracking polls will start to move back to Obama on Tuesday, as the Republican convention reaction days start to cycle out of the polls. The two pieces of hope that I keep holding onto are that Republicans could be going through a bounce period right now that will inevitably fade, and also that the Gallap and Rasmussen polls have consistently been 3.2%-3.4% more favorable to McCain than all other polling firms combined. If those are both true, than a narrow tracking poll lead for Obama is actually decent news, as it means that Obama is ahead by about 3.0-3.5% nationally, and soon to be even more. Factors that worry me include Republicans closing the partisan self-identification gap to only 5.7%, and that Obama supposedly polls better on the weekends (although I can't seem to find a link confirming that rumor).
Phew. These weren't exactly the numbers I wanted, but they also aren't terrible. At least the morning shakes are over now. How are you feeling about these polls?
