Prosecuting Attorney
August 4, 2026 · Clay County, Missouri · County · 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 · 21 out of 100
This district is large for its type, so each vote is a smaller slice of the outcome. About 258,122 people live here.
score = 100 × ln(largest population ÷ this district's) ÷ ln(largest ÷ smallest), rounded to 2 decimals = 100 × ln(995,569 ÷ 258,122) ÷ ln(995,569 ÷ 1,934) = 21.62, comparing counties in MO (grades: 66+ high, 33+ average, otherwise low)
Decisiveness: None · only 1 candidate
One candidate is running unopposed, so votes can't change the outcome.
Low representation + an uncontested race → Very low vote impact.
