Seats-to-Votes Distortion Rankings
Seats-to-Votes Distortion: Measure of the average by which one party wins a greater percentage of seats than votes and the other party wins a smaller percentage of seats than votes. The distortion is calculated by adding the percentage distortion for each party and then dividing by two. For example, if Democratic candidates won 10% more House seats than votes and Republicans won 6% fewer House seats than their share of the House votes, the seat-to-vote distortion would be 8%.
