Member of the State Assembly, District 10
November 3, 2026 · Assembly District 10; California · State 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 · 11 out of 100
This district is large for its type, so each vote is a smaller slice of the outcome. About 522,465 people live here.
score = 100 × ln(largest population ÷ this district's) ÷ ln(largest ÷ smallest), rounded to 2 decimals = 100 × ln(531,388 ÷ 522,465) ÷ ln(531,388 ÷ 457,211) = 11.26, comparing state house districts in CA (grades: 66+ high, 33+ average, otherwise low)
Decisiveness: Unknown
