Accuracy Of Polls a Question In Itself

[Washington Post] 30 Oct 2008--Could the polls be wrong?

Sen. John McCain and his allies say that they are. The country, they say, could be headed to a 2008 version of the famous 1948 upset election, with McCain in the role of Harry S. Truman and Sen. Barack Obama as Thomas E. Dewey, lulled into overconfidence by inaccurate polls.

"We believe it is a very close race, and something that is frankly very winnable," Sarah Simmons, director of strategy for the McCain campaign, said yesterday.

Few analysts outside the McCain campaign appear to share this view. And pollsters this time around will not make the mistake that the Gallup organization made 60 years ago -- ending their polling more than a week before the election and missing a last-minute surge in support for Truman. Every day brings dozens of new state and national presidential polls, a trend that is expected to continue up to Election Day.

Still, there appears to be an undercurrent of worry among some polling professionals and academics. One reason is the wide variation in Obama leads: Just yesterday, an array of polls showed the Democrat leading by as little as two points and as much as 15 points. The latest Washington Post-ABC News tracking poll showed the race holding steady, with Obama enjoying a lead of 52 percent to 45 percent among likely voters.
