Bias in Polls
On Polipundit, DJ Drummond has posted some research into the bias in various national polls. He posted greater detail on his own blog.
His results certainly make me wonder about CBS News's polling techniques. They have huge aggregate variability, an apparent bias against Bush that's bigger than their margin of error, and when they work with Gallup and USA Today they still have a large aggregate variability, but the bias goes the opposite way and to a smaller degree. When they poll with the New York Times, they have an apparent anti-Bush bias as well, but not to such a large degree and not with so much aggregate variability.
