Gallup and New Coke

DJ Drummond explains why the polls are wrong.

The polls are wrong this year, very wrong. I have been saying this for months, and I have backed up my claim with both statistical and anecdoctal support. The claims I have made have inspired some, caused others to laugh in derision, and brought others to test their assumptions and revisit the hard data. Along the way, there have been a lot of questions about how and why the polls could be wrong. The most common complaint, is that for all of the polls to be wrong, there would need to be some sort of conspiracy, or else an incredibly stupid decision made across the board. Well, I am not a big believer in conspiracies, but I do think that the polling groups have fallen into a groupthink condition.
...
So, could I be wrong? I have to be honest and admit that I could. But in that case, we'd have to ask why the polls do not generally agree with each other, why Gallup is trying to spin three different models at the same time to get a grasp of the picture, why McCain and Obama are both so interested in Pennsylvania, yet neither is working very hard in Ohio right now. We'd have to explain why McCain-Palin rallies are now attracting thousands more people than Obama-Biden rallies, why Letterman suddenly found it cool to have McCain on his show and SNL decided they wanted Palin on theirs. We'd have to explain why there are not a lot of Obama signs visible, but we hear about his army of lawyers getting ready. We'd have to explain why McCain and Palin appear to be so relaxed while Obama and Biden look like they're worried.

What I think is happening, is this - the polls' headquarters were based deep in liberal territory, where the assumption was that Obama's candidacy would actually create a groundswell of pro-democrat voters unseen in the country since 1932. That McCain is more experienced with the key issues than Obama was ignored, that the historical significance of the debates shows that the effects appear several weeks later was also ignored. That the economy could be as reasonably blamed on the democrat-controled Congress as on the republican President was never considered. That character would be a salient factor in the decisions of voters was rejected out of hand.

The polls are wrong. Make your own mind up, because your vote will matter.
