State Representative Pos. 1
August 4, 2026 · Legislative (House) District 20; Washington · State house district · 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: Low · 9 out of 100
This district is large for its type, so each vote is a smaller slice of the outcome. About 163,631 people live here.
score = 100 × ln(largest population ÷ this district's) ÷ ln(largest ÷ smallest), rounded to 2 decimals = 100 × ln(164,798 ÷ 163,631) ÷ ln(164,798 ÷ 152,644) = 9.28, comparing state house districts in WA (grades: 66+ high, 33+ average, otherwise low)
Decisiveness: Unknown
