“While 2000 was generally a fairly rough year for pollsters, who had to deal with an unenthusiastic electorate, some third-party challengers, and some late-breaking developments like Bush’s DUI charge, Rasmussen was the worst of the lot, missing by an average of 5.7 points. They also called 7 states wrong.** Some of this was the result of bias, as they were 3.5 points too high on Bush’s margin in the states they surveyed, on average.”
