About This Blog

Welcome! My name is Nicolas Nevins, and I have created a mathematical formula intended to predict the results of US House Elections. I developed the formula over the past year, and it was quite accurate when retroactively applied to the 2012 and 2014 House elections (the only ones so far fully in the SuperPAC era). The formula includes many components that are believed to help predict the winner of US House races, such as fundraising, independent expenditures, partisanship of a district, and incumbency, among others. On this blog, I will publish and update my predictions for the 2016 elections.

11/07 Ratings Update - FINAL

Here are my final race ratings for the 2016 House elections. Democrats are projected to pick up between 16 and 30 seats, with an average outcome of 23 pickups. As a result, if Democrats win every race that they are expected to win (Tilt Democrat or better), and they win every Toss-Up, they will win an extremely slim House majority of 218-217. However, this is not a likely scenario, as Toss-Ups are expected to be won approximately equally by both parties. As a result, the most likely result after the elections on Tuesday is a Republican majority of 5-10 seats. Nevertheless, a very slim Democratic majority is within the realm of possibility.
