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: High · 68 out of 100
This district is a small slice of its state, so each vote here carries much more weight than a vote in a statewide race. About 63,061 people live here.
Show the representation math
score = 50 + 50 × ln(state population ÷ this district's) ÷ ln(50,000) = 50 + 50 × ln(3,210,507 ÷ 63,061) ÷ ln(50,000) = 68.16, measured against a statewide vote in IA (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.
High representation + an uncontested race → My vote power: Below average.
