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 · 39 out of 100
This district is mid-sized for its type, so each vote carries average weight. About 58,054 people live here.
score = 100 × ln(largest population ÷ this district's) ÷ ln(largest ÷ smallest), rounded to 2 decimals = 100 × ln(62,855 ÷ 58,054) ÷ ln(62,855 ÷ 51,492) = 39.85, comparing state senate districts in ID (grades: 66+ high, 33+ average, otherwise low)
Decisiveness: Unknown
No past results for this contest yet.
