United States Representative, Congressional District 9
November 3, 2026 · Congressional District 9 (119th Congress), Arizona · U.S. House district · general
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 · 26 out of 100
This district is large for its type, so each vote is a smaller slice of the outcome. About 863,227 people live here.
score = 100 × ln(largest population ÷ this district's) ÷ ln(largest ÷ smallest), rounded to 2 decimals = 100 × ln(1,021,191 ÷ 863,227) ÷ ln(1,021,191 ÷ 546,488) = 26.88, comparing all US House districts nationwide (grades: 66+ high, 33+ average, otherwise low)
