Sheriff
August 6, 2026 · Knox County, Tennessee · County · 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 494,148 people live here.
score = 100 × ln(largest population ÷ this district's) ÷ ln(largest ÷ smallest), rounded to 2 decimals = 100 × ln(919,173 ÷ 494,148) ÷ ln(919,173 ÷ 5,079) = 11.94, comparing counties in TN (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.
