AP: “The one thing most likely to conjure nightmares of the 2016 election night for opponents of President Donald Trump is the Needle. A graphic on The New York Times’ website, the Needle measured in real time the probability of victory for Trump or Hillary Clinton as votes were counted. Its steady movement triggered anxiety for Clinton supporters, who repeatedly refreshed the page, and elation for Trump fans.”
“The Needle won’t be making a reappearance on Nov. 3, one change in the world of election probability gurus following the unexpected 2016 result. Nate Silver’s influential FiveThirtyEight blog used a number, not a needle, for the same task four years ago but won’t on election night 2020. Silver said the change had more to do with uncertainties created by the high volume of early voting this year than any failures in 2016. ‘I just think people need to be exceptionally careful,’ he said. Silver has been a pioneer in the specialized field of statistic experts who crunch the growing number of public opinion polls to put them in a broader context. Nate Cohn of the Times and his blog The Upshot, is also a leader. They amplified the shock of 2016 by predicting a high probability of a Clinton victory. Cohn went into election night saying Clinton had an 85% chance of winning, and that served as the Needle’s baseline. The graphic was a meter, shaped like a half-clock, with outcomes that ranged from a ‘very likely’ Clinton win to the same for Trump.”
