1Voter Voice Score is obtained by taking the state’s average ranking in key categories:
- Average margin of victory (measuring competitiveness)
- Percentage of landslide victories (measuring competitiveness)
- Partisan skew (measuring how well the intent of voters was reflected by the results)
- Voter consensus (a measure of efficacious participation)
- Voter turnout (a measure of participation)

3Margin of Victory: Measures the average difference between the winner’s percentage of the vote and the second-place candidate’s percentage of the vote.
10
4Landslide Victories: Measures the percentage of races won by a margin of victory of 20% or greater. Uncontested races are considered landslides for this purpose.
11
5Voter consensus: Measures the percentage of voting age population who voted for the winning candidate in US House elections. The value is determined by dividing the percentage of votes cast for winning candidates with the total voting age population
12
6Partisan skew: Measures 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 skew is calculated by adding the percentage skew for each party and then dividing by two. For example, if Democratic candidates won 10% more House seats than their share of votes and Republicans won 6% fewer House seats than their share of votes, the partisan skew would be 8%.

7Voter Turnout: Measures the percentage of the voting age population who voted in a state’s US House elections (as opposed to statewide and presidential elections). We use population estimates by Professor Michael McDonald from electproject.org
