Varying Polls

November 6. 2008

According to an article, Rasmussen Reports was one of the two most accurate polls during the 2008 U.S. presidential election. However, on the Saturday before the election, it stated McCain was leading. Something in the election shifted during the last days.

John McCain (Republican)

I questioned the polls in articles during the weeks leading up to the election, as they all varied so wildly and at times with no definitive speech by a candidate, event or incident in the campaign to justify the upturns and downturns. Read this:

The List: Which presidential polls were most accurate?

The Pew Research Center and Rasmussen Reports were the most accurate in predicting the results of the 2008 election, according to a new analysis by Fordham University political scientist Costas Panagopoulos. The Fordham analysis ranks 23 survey research organizations on their final, national pre-election polls, as reported on pollster.com.

On average, the polls slightly overestimated Obama's strength. The final polls showed the Democratic ahead by an average of 7.52 percentage points -- 1.37 percentage points above his current 6.15-point popular vote lead. Seventeen of the 23 surveys overstated Obama's final victory level, while four underestimated it. Only two -- Rasmussen and Pew -- were spot on.
