PlanScore bases its scores on predicted precinct-level votes for North Carolina U.S. Congressional races built from past election results and U.S. Census data.

This model includes predictions for open seat races as well as major-party incumbents, if provided.
We obtained all results from North Carolina’s State Board of Elections and entered them into our ordinary least squares regression model:
