State Senator - District No. 21
July 21, 2026 · State Senate District 21; Arizona · State senate 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 · 50 out of 100
This district is mid-sized for its type, so each vote carries average weight. About 246,628 people live here.
score = 100 × ln(largest population ÷ this district's) ÷ ln(largest ÷ smallest), rounded to 2 decimals = 100 × ln(275,769 ÷ 246,628) ÷ ln(275,769 ÷ 221,081) = 50.53, comparing state senate districts in AZ (grades: 66+ high, 33+ average, otherwise low)
