How do we calculate my vote power?

What goes into the 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 the number of candidates.

Representation: Normal · 61 out of 100

This district covers a large share of its state, so each vote carries about average weight — like a vote in a statewide race. About 535,075 people live here.

Show the representation math

score = 50 + 50 × ln(state population ÷ this district's) ÷ ln(50,000) = 50 + 50 × ln(7,044,056 ÷ 535,075) ÷ ln(50,000) = 61.91, measured against a statewide vote in MA (grades: 66+ high, 33+ normal, otherwise low; a statewide race is the 50 baseline)

Decisiveness: None · only 1 candidate

One candidate is running unopposed, so votes can't change the outcome.

Normal representation + an uncontested race → My vote power: Below average.
