Election 2012 – Last Look at the Predictions

President Obama has been sworn into office for his second term. So, how did the predictors do? Here are some assessments:

  • Fact: Nate Silver Predicts Election Outcome, Becomes Nerdy Chuck Norris, Wired
  • Pollsters and Pundits: Who Got the Presidential Election Right and Who Didn’t: A Reckoning U.S. News
  • Keeping Track: Pundits and Pollsters and Their Presidential Predictions U.S. News
  • Among the top election quants, Nate Silver reigns supreme c/net

These look at the accuracy of the vote percentage.  But, I’m wondering which ones I should use in 2016 to get a sense of which states are “in play.” Looking at the results there were 15 states and Nebraska’s 2nd CD where the winner won by less than 10%, i.e. state-in play, before the election. came the closest to identifying these states.  The site identified all 15 states.  However, identified another 5 states as being in play.  Huffington Post identified 10 of the states.  NYT: FiveThirtyEight identified 7 of the states and Nebraksa’s 2nd CD.  Real Clear Politics identified all 15 states, but also identified 10 more.

Here is the “states in play” table from my Nov. 8th post, The Day After – Looking a the the Predicitions, with the official results1.
