Nate Silver's "Aggressive" Polling Average Shows Significant Swing To Harris

US

Election analyst Nate Silver's polling averageshows that Vice President Kamala Harris has improved on President Biden's polling numbers by, "somewhere between 3.9 points and 8.5 points in literally every swing state — and by more than 7 points nationally."

  • Silver notes on X: "...while some of the other polling averages out there are great too, ours is a little more aggressive & often the quickest to pick up on trends."
  • Silver draws two conclusions from the polling data: Firstly, that "Harris’s largest gains have come in Arizona, which supports the theory that her relative strengths are in the Sunbelt rather than the Rust Belt."
  • Secondly, on whether Harris faces a larger Electoral College-popular vote gap than Biden because "her relative gains over Biden are larger in national polls than in most of the swing states."
  • Silver notes: "Actually not. While that was true when we first relaunched the model, Harris now actually has a smaller gap than Biden. In simulations where Harris wins the popular vote between 1 and 2 percentage points, for instance, we have her winning the Electoral College 51 percent of the time, versus 34 percent in the final Biden forecast."
  • For context, the New York Times polling average, which relies more heavily on data from "select pollsters", ticked up today to Harris 49-47% after a week showing Harris leading Trump 48-47%, despite a raft of positive polling for Harris.
