How do we calculate my vote power?
What determines the vote power rating for ballot measures: Representation: how much weight one vote carries here compared with a statewide vote — the smaller the district, the more each vote counts. You have more power in ballot measures because you vote directly on the policy.
Representation: Average · 50 out of 100
This district covers a large share of its state, so each vote carries about average weight — like a vote in a statewide race. About 6,191,814 people live here.
Show the representation math
score = 50 + 50 × ln(state population ÷ this district's) ÷ ln(50,000) = 50 + 50 × ln(6,191,814 ÷ 6,191,814) ÷ ln(50,000) = 50, measured against a statewide vote in MO (grades: 66+ high, 55+ above average, 33+ average, otherwise low; a statewide race is the 50 baseline)
Average representation + a direct vote on the policy → My vote power: Above average.
Ballot Measure
Voters decide whether to keep House Bill 1, a 2025 law that replaces Missouri's U.S. House district map with new boundaries. Your congressional district may change; the state says it has no effect on taxes.
