Here’s Proof Some Pollsters Are Putting A Thumb On The Scale

Introduction by Ken Feltman:

This is perhaps the most important news about political polls to come out of the 2016 election: Nate Silver and others at FiveThirtyEight have the statistics to establish that some pollsters, intentionally or not, skew their results.

Earlier this year, my colleague Harry Enten documented evidence of pollster “herding” — the tendency of polling firms to produce results that closely match one another, especially toward the end of a campaign. What’s wrong with the polls agreeing with one another? The problem is that it’s sometimes a case of the blind leading the blind.
