About this project
Like most forecasting models, Election Lab uses the past to predict the future. To predict House and Senate elections in 2014, we draw on the elections from 1980-2012. We first look at how well key factors were related to outcomes in those past elections. Then, we gather information about those same factors for 2014. Assuming that these factors will be related to election outcomes in 2014 in the same way they were from 1980 to 2012, we can make a prediction about who will win each race.
