Constitutional Amendment J: Citizenship Voting Requirement
November 3, 2026 · South Dakota · 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: High · 89 out of 100
Smaller districts give each vote more weight, and this district is small for its type. About 907,428 people live here.
score = 100 × ln(largest population ÷ this district's) ÷ ln(largest ÷ smallest), rounded to 2 decimals = 100 × ln(39,287,377 ÷ 907,428) ÷ ln(39,287,377 ÷ 582,397) = 89.47, 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.
High representation + a ballot-measure boost → Very high vote impact.
