President of the Cook County Board of Commissioners
November 3, 2026 · Cook County, Illinois · 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 · 0 out of 100
This district is large for its type, so each vote is a smaller slice of the outcome. About 5,182,090 people live here.
score = 100 × ln(largest population ÷ this district's) ÷ ln(largest ÷ smallest), rounded to 2 decimals = 100 × ln(5,182,090 ÷ 5,182,090) ÷ ln(5,182,090 ÷ 3,605) = 0, comparing counties in IL (grades: 66+ high, 33+ average, otherwise low)
Decisiveness: Unknown
No past results for this contest yet.
Low representation + unknown decisiveness → Below average vote impact.
