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
The legislature could not change or repeal a law that voters passed by petition unless 80% of both chambers agree and voters approve. It also makes the petition process a basic right and keeps today's signature and majority-vote rules; the state says it will not raise or lower taxes.

A YES vote means
Lawmakers could not change voter-passed laws without an 80% vote of both chambers and a public vote, and could not pass laws that make petitions harder.
A NO vote means
The constitution stays the same. Citizens keep today's right to propose laws and referendums, and lawmakers can still change voter-passed laws.
