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.

10/26 Ratings Update

Here are my rating changes for the week of 10/24. I am sorry that it is 2 days late; I have been out of town for the past 4 days. Although there are several changes, the overall picture remains exactly the same, with Democrats predicted to pick up about 20 seats. If Democrats want to have a serious chance of retaking the House, they will need to move beyond the races that they are currently targeting and begin to target some of the Tilt/Leans Republican races.
