- It's Zogby, one of the historically most inaccurate polling agencies in a year where all polling seems woefully biased.
- A one-point lead is statistically meaningless. Obama by 2 with MOE of 3 says the same thing, for the most part.
Those last two words I think are the important ones. While Obama +2 or McCain +1 statistically are the same, emotionally the term "McCain lead" gets people interested. From the search terms, most people were just interested in verification. But you could see some people looking for evidence not to believe the poll--searches such as "Zogby poll innaccurate don't trust".
Hugh Hewitt suggests:
The shocker of a one-point lead for McCain in the Zogby national tracking poll for Friday will energize the GOP 96 hour effort everywhere.In an environment where media, polling agencies, and $600 million of Obama's own advertising have painted a picture of inevitablilty of President Obama, it is remarkable how much interest one random sample generates. All because--as statistically meaningless as it is--people can say with no deception the phase "McCain lead" going in to the final weekend before the election.
