How can Zogby have the race even? He seems like a reasonable fellow although some have spotted a distinct Democrat bias. But can he skew his poll without every sampler on earth being aware of it?
Zogby's MO is to post outliers that favor his candidate right up until the last poll before the election. That is the only Zogby poll you know he wants to get right. Of course, he did not fare well in 2002. Now, his internet polls are pure garbage as the participants are self-selected.
Zogby controls for D/R party ID based on 2000 numbers. Not a good way to weight a poll. He also fudges his numbers based on the latest political wind. Remember, he said that "this race was for Kerry to lose" so he needs to come up with numbers to support his case.
