September 1, 2026 · Massachusetts · Statewide · primary
How do we calculate vote impact?
Vote impact = representation (how much weight one vote carries here, the smaller the district's population, the higher the representation) + decisiveness (how likely this race is to be close, based on past results and number of candidates).
Representation: Average · 40 out of 100
This district is mid-sized for its type, so each vote carries average weight. About 7,044,056 people live here.
score = 100 × ln(largest population ÷ this district's) ÷ ln(largest ÷ smallest), rounded to 2 decimals = 100 × ln(39,287,377 ÷ 7,044,056) ÷ ln(39,287,377 ÷ 582,397) = 40.81, comparing all statewide districts nationwide (grades: 66+ high, 33+ average, otherwise low)
