Ranking the Accuracy of the Pre-Election Polls

| | Comments (0)

The Pew Research Center and Rasmussen Reports topped the list of pollsters for accuracy in their final projections for the presidential campaign, according to a study by political scientist Costas Panagopoulos of Fordham University.

Panagopoulos said that "for all the derision directed toward pre-election polling, the final poll estimates were not far off from the actual nationwide voteshares for the two candidates," Panagopoulos said. "On average, pre-election polls from 23 public polling organizations projected a Democratic advantage of 7.52 percentage points on Election Day, which is only about 1.37 percent points away" from Obama's 6.15 margin in the popular vote.
