Nate Silver’s FiveThirtyEight website has released their 2016 edition of pollster ratings.
Just like two years ago, a number of PA based firms were included.
Franklin & Marshall College came in second with a B+. Eighteen surveys were included that had a success rate of 94% and a MRB of R+0.4.
There was a three-way tie for third. The particulars of which are included below:
