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 · 1 out of 100
This district is large for its type, so each vote is a smaller slice of the outcome. About 659,844 people live here.
score = 100 × ln(largest population ÷ this district's) ÷ ln(largest ÷ smallest), rounded to 2 decimals = 100 × ln(742,999 ÷ 659,844) ÷ ln(742,999 ÷ 724) = 1.71, comparing counties in CO (grades: 66+ high, 33+ average, otherwise low)
