VOTECC = 48.53 - .482*INFLATIONCC + .710*(15/7)*GOODNEWSCC
VOTECC = Democratic share of the two-party House vote in 2014.
INFLATIONCC = The growth rate of the GDP deflator in the first 7 quarters of the second Obama administration, 2013:1-2014:3, at an annual rate.
GOODNEWSCC = The number of quarters in the first 7 quarters of the Obama administration in which the growth rate of real per capita GDP is greater than 3.2 percent at an annual rate.
These values lead to a predicted Democratic vote share of 50.85
percent

“We rely on statistical models for many decisions every single day, including, crucially: weather, medicine, and pretty much any complex system in which there’s an element of uncertainty to the outcome. In fact, these are the same methods by which scientists could tell Hurricane Sandy was about to hit the United States many days in advance.
Dismissing predictive methods is not only incorrect; in the case of electoral politics, it’s politically harmful.”
— Zeynep Tufekci, “In Defense of Nate Silver, Election Pollsters, and Statistical Predictions”
