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 5,862,189 people live here.
Show the representation math
score = 50 + 50 × ln(state population ÷ this district's) ÷ ln(50,000) = 50 + 50 × ln(5,862,189 ÷ 5,862,189) ÷ ln(50,000) = 50, measured against a statewide vote in CO (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: Healthcare Affordability, Public Education Quality
Colorado would replace its flat 4.4% income tax with rates from 3.7% on income under $25,000 up to 8.4% on income over $1 million, raising about $2.7 billion a year for schools, health care and child care. People earning under $100,000 would pay a bit less; those over $500,000 would pay more.
A YES vote means
Starting in 2027, income tax rates rise with income: lower than today on the first $100,000, higher on income above $500,000. The extra money goes to schools, health care and child care.
A NO vote means
Everyone keeps paying the same flat 4.4% income tax rate, and the state does not get the extra $2.7 billion a year.
