How do we calculate my vote power?
What goes into the 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
Supports: Personal Income Tax Reduction
Missouri lawmakers would have to phase out the individual income tax when state revenue grows. They could tax more goods and services or raise sales-tax rates if the same law offsets that revenue with income-tax cuts. Local governments would later cut certain local taxes, but not in a way that reduces public-school funding. Future tax effects are unknown.

A YES vote means
The Constitution would require an income-tax phaseout and allow broader sales taxes tied to income- and local-tax cuts.
A NO vote means
The Constitution would keep its current tax rules. Lawmakers would not receive this new authority or income-tax phaseout requirement.
