A Democratic Majority

Our 2018 House Predictions show the Democrats have a 95.3% chance of winning the House.

PoliticalEdu's 2018 midterm predictions present three models for the House of Representatives, each assuming different levels of gerrymandering.  

The first model assumes Democrats need to win the House popular vote by 8.5 points to be considered even money for the House majority.  In 2016, the decisive House district favored the Republican Party by 5.5 points -- model two uses that as the popular vote margin by which Democrats need to win to have a 50 percent chance of winning the House. 

Lastly, we create a 2018 House prediction that assumes no gerrymandering effect outside of that baked into previous elections.
