The most accurate polls in the 2008 presidential election

From Costas Panagopoulos, Ph.D. at Fordham University.  He writes:
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. 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 percentage points away from the current estimate of a 6.15-point Obama margin in the national popular vote. . . .
