United States Senator
September 8, 2026 · New Hampshire · Statewide · primary
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 · 79 out of 100
Smaller districts give each vote more weight, and this district is small for its type. About 1,394,868 people live here.
score = 100 × ln(largest population ÷ this district's) ÷ ln(largest ÷ smallest), rounded to 2 decimals = 100 × ln(39,287,377 ÷ 1,394,868) ÷ ln(39,287,377 ÷ 582,397) = 79.26, comparing all statewide districts nationwide (grades: 66+ high, 33+ average, otherwise low)
