Daniel Terdiman ranks the poll-collecting mathletes:
Silver wasn't the only one to do exceptionally well in the prediction department. In fact, each of the five aggregators that CNET surveyed yesterday — FiveThirtyEight, TPM PollTracker, HuffPost Pollster, the RealClearPolitics Average, and the Princeton Election Consortium — successfully called the election for Obama, and save for TPM PollTracker and RealClearPolitics handing Florida to Romney, the aggregators were spot on across the board when it came to picking swing state victors.
But, overall, Silver still reigns supreme:
In addition to picking the winner in all 50 states — besting his 49 out of 50 slate in 2008 — Silver was also the closest among the aggregators to picking the two candidates' popular vote percentages. All told, he missed Obama's total of 50.8 percent by just four-tenths of a percentage point (50.4) and Romney's 48 percent by just three-tenths of a point (48.3) for an average miss of just 0.35 percentage points. HuffPo Pollster and RealClearPolitics tied for second with an average miss of 0.85 points.
