Constitutional Amendment 3: Abortion and Gender Transition Procedure Restrictions
November 3, 2026 · Missouri · Statewide
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 · 43 out of 100
This district is mid-sized for its type, so each vote carries average weight. About 6,191,814 people live here.
score = 100 × ln(largest population ÷ this district's) ÷ ln(largest ÷ smallest), rounded to 2 decimals = 100 × ln(39,287,377 ÷ 6,191,814) ÷ ln(39,287,377 ÷ 582,397) = 43.87, comparing all statewide districts nationwide (grades: 66+ high, 33+ average, otherwise low)
Ballot measure: +1 step
Your vote sets the policy directly, so the rating gets a one-step boost.
Average representation + a ballot-measure boost → High vote impact.
