Tennessee Senate District 21
August 6, 2026 · State Senate District 21; Tennessee · 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 · 56 out of 100
This district is mid-sized for its type, so each vote carries average weight. About 210,231 people live here.
score = 100 × ln(largest population ÷ this district's) ÷ ln(largest ÷ smallest), rounded to 2 decimals = 100 × ln(228,447 ÷ 210,231) ÷ ln(228,447 ÷ 197,150) = 56.4, comparing state senate districts 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.
Average representation + an uncontested race → Below average vote impact.
