How do we calculate my vote power?
What determines the vote power rating: Representation: how much weight one vote carries here compared with a statewide vote — the smaller the district, the more each vote counts. Decisiveness: how likely this race is to be close, based on past results or current analyst ratings, plus whether more candidates are running than there are seats.
Representation: Average · 50 out of 100

Show the representation math
score = 50 + 50 × ln(state population ÷ this district's) ÷ ln(50,000) = 50 + 50 × ln(7,044,056 ÷ 7,044,056) ÷ ln(50,000) = 50, measured against a statewide vote in MA (grades: 66+ high, 55+ above average, 33+ average, otherwise low; a statewide race is the 50 baseline)
