Scores describe shape, not intent. How scores work
Michigan's senators
- Gary C. Peters, DemocratSeat on the November 3, 2026 ballot: results aren't available yet.
- Elissa Slotkin, Democrat
Senators are elected by the whole state, so district lines don't change who they are. Senators serving as of November 6, 2026. Senators elected in November 2026 take office January 3, 2027. Where this comes from
Partisan fairness
How the 2024 presidential vote splits across these districts. Kamala Harris (Democrat) won 49.3% of the two-party vote and carried 5 of 13 districts.
- Efficiency gap
- 12.5% Favors Republicans
Counts each party's wasted votes: votes for a losing candidate, plus a winner's votes beyond the half needed to win. The gap is the difference between the two parties' wasted votes, as a share of all votes.
- Mean-median difference
- 1.1 points Favors Republicans
The gap between a party's average vote share across the districts and its share in the middle (median) district. When the middle district leans away from a party's average, that party's voters are packed into a few lopsided districts.
- Declination
- 0.22 Favors Republicans
Compares how lopsided each party's wins are. A party that wins a few districts by huge margins and loses the rest narrowly is at a disadvantage. Runs from 0 (even) to 1.
Votes are 2024 presidential results by precinct, added up within each district. This state used the same districts in 2024 and 2026. These measures show how a map turns one election's votes into seats. They don't show why the lines were drawn, and they shift from one election to the next. How fairness scores work
