How do we calculate my vote power?
What goes into the rating: Representation: how much weight one vote carries here compared with a statewide vote — the smaller the district, the more each vote counts. Decisiveness: how likely this race is to be close, based on past results or current analyst ratings, plus the number of candidates.
Representation: Normal · 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, 33+ normal, otherwise low; a statewide race is the 50 baseline)
Normal representation → My vote power: Normal.
Ballot Measure
Opposes: Civil Rights, Women's Reproductive Rights
Constitutional Amendment 3 would repeal the abortion-rights amendment Missouri voters approved in 2024 and instead prohibit abortion except to protect the life of the mother, or up to 12 weeks in cases of rape or incest, and prohibit gender-transition procedures for minors.
A YES vote means
A yes vote repeals the 2024 abortion-rights amendment and enacts new abortion restrictions and a ban on gender-transition procedures for minors.
A NO vote means
A no vote keeps the current constitutional right to reproductive freedom adopted in 2024.
