Arizona State Representative, District 30
July 21, 2026 · State House District 30; Arizona · 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: Average · 52 out of 100
This district is mid-sized for its type, so each vote carries average weight. About 245,615 people live here.
score = 100 × ln(largest population ÷ this district's) ÷ ln(largest ÷ smallest), rounded to 2 decimals = 100 × ln(275,769 ÷ 245,615) ÷ ln(275,769 ÷ 221,081) = 52.39, comparing state house districts in AZ (grades: 66+ high, 33+ average, otherwise low)
