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: Above average · 64 out of 100
This district is a good deal smaller than its state, so each vote here carries more weight than a vote in a statewide race. About 44,658 people live here.
Show the representation math
score = 50 + 50 × ln(state population ÷ this district's) ÷ ln(50,000) = 50 + 50 × ln(1,021,191 ÷ 44,658) ÷ ln(50,000) = 64.46, measured against a statewide vote in DE (grades: 66+ high, 55+ above average, 33+ average, 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.
Above average representation + an uncontested race → My vote power: Below average.
