Three days ago, I was feeling nervous about a sudden seeming lurch-let towards McCain in the daily tracking polls. This in spite of repeated posts by the experts insisting that there was no actually meaningful tightening going on, it was mostly just a question of statistical artifacts.
By this morning, Pollster.com’s status update did acknowledge that there had been some movement: “If you look at our national trend chart, we definitely show a narrower Obama margin now (5.4% as of this writing) than about a week ago.” Obama’s current national trend estimate, Mark Blumenthal explains, now stands about a point lower than his high of 50.9% a week ago, and McCain’s current estimate is slightly less than two percentage point higher than his low of 42.2% on October 12.
However, there’s still little to worry about, basically, as he points out the obvious to calm our nerves: “[T]ime is short and Obama’s lead still looks daunting. [..] Obama continues to lead on every national poll and yesterdays tracking updates show no decisive shift in either direction.”
Today’s tracking poll numbers certainly help sooth the jitters, as most actually show movement towards Obama (see Chart 1). Over the last two days, the ABC/WaPo, IBD/TIPP and Rasmussen daily trackers all have Obama’s lead back up 1 point, Zogby has it up 2, and the Gallup samples have moved back in Obama’s favour too: the regular voter and expanded likely voter samples both by 2 points and the traditional likely voter sample by no less than 5 (from 3% to 8%).
The result is that the average of all daily tracking polls has Obama’s lead back up by 1 point from +5.6% to +6.6%, after it had fallen by 2.7 points in the previous four days.
