What's With The Polls?

The polls are all over the place. Earlier today IBD said it is tied, while NPR had a segment about how Bush is way ahead. What is going on? The folks at the Electoral Vote site posted an opinion today.

Some bad news for the polling business. Strategic Vision (R) has a new poll in Ohio showing Bush ahead 52% to 43% there. However, there is also a Lake Snell Perry (D) poll showing the race there to be an exact tie, with both candidates at 46%. It is becoming increasingly clear that the pollsters are producing the results that the people paying the bills want to hear. Even pollsters who were once thought to be above suspicion are now suspicious. Gallup, for example, is now normalizing its samples to include 40% Republicans, even though the 2000 exit polls showed the partisan distribution to be 39% Democratic, 35% Republican. There is scant evidence that the underlying partisan distribution has changed much since then. Other pollsters also normalize their data, but most don't say how. Normalizing the sample to ensure the proper number of women, elderly voters, etc. is legitimate provided that the pollster publicly states what has been done.
