Before the 2012 presidential election, the statistician Nate Silver gave Barack Obama a chance of “more than 70 per cent,” and then “north of 90 per cent.” MSNBC host Joe Scarborough called Silver “a joke.” He said anyone who thought the race was “anything but a tossup right now” was “such an ideologue.”
Silver’s forecast called the result correctly in all 50 states. In 2008 he had called 49 of the 50, missing only Indiana.
