Exceptionally Low Turnout Can Account For Polling Errors

November 10th, 2014, 9:26am by Sam Wang

Today, in The American Prospect, I detail how this year’s polling errors are correlated with voter turnout, which was the lowest since 1942, as based on Michael McDonald’s tabulation [...]

The Midterm Polling Curse (Morning-after edition)

November 5th, 2014, 11:41am by Sam Wang

Pre-election PEC Senate aggregate: 52 Republican seats. Outcome: 52 or more Republican seats (Alaska is not called, and Louisiana goes to a runoff). As I wrote in The New Republic, last night’s performance by the GOP was remarkable. In close Senate races, Republicans outperformed polls by an average of 5.3 percentage points. Prime examples of [...]

Errors Are Inevitable – But Who Will Benefit?

November 4th, 2014, 2:00pm by Sam Wang

Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0],p=/^http:/.test(d.location)?’http’:'https’;if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src=p+’://platform.twitter.com/widgets.js’;fjs.parentNode.insertBefore(js,fjs);}}(document, ‘script’, ‘twitter-wjs’); Despite the certainty of pundits, we actually don’t know who will win the Senate! In The New Yorker, I explain. From 2004 to 2012, only thirteen Senate races have had margins of less than three percentage points in the week before the election. Of these, four were won by the [...]
