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.

10/10 Ratings Update

I have a few rating changes to report this week, mostly as a result of outside spending in races. Next week, 3rd quarter campaign finance reports are due to the FEC by Saturday (10/15), and they likely will not all be processed for a few days afterwards. I will not be posting a ratings update next week until all 3rd quarter report data is available through the FEC, which could be Tuesday or Wednesday.
