Colorado voters will decide 14 statewide measures in November, including proposals to overhaul income taxes, increase penalties for fentanyl offenses and restrict transgender people’s rights. Thirteen measures qualified through citizen initiatives, while state lawmakers referred one to the ballot, according to the Secretary of State’s Office. Four proposals address taxes and government spending. Proposition 136 would lock Colorado’s flat income tax rate at its current 4.4%. Amendment 87 would replace the flat tax with graduated rates, raising taxes on households earning more than $500,000 a year while lowering them for lower-income households. Supporters estimate it would raise about $2 billion in its first year for education, health care and child care, with that revenue exempt from state spending limits under the Taxpayer’s Bill of Rights, or TABOR. If both tax measures pass, the one receiving more votes would determine whether the 4.4% rate cap remains in effect. Proposition NN would let the state keep and spend at least an estimated $4.5 billion that otherwise would be refunded to taxpayers under TABOR. The money would go to education and children’s programs during the first decade; lawmakers would decide how to use it afterward. Proposition 137 would dedicate taxes on sporting goods and outdoor equipment—estimated at about $175 million annually—to wildfire mitigation and conservation. Three proposals concern criminal justice and law enforcement. Proposition 132 would make possession of any amount of fentanyl a felony, punishable by up to eight years in prison, and allow sentences of up to 32 years for distribution. A person found with less than one gram could have the charge reduced to a misdemeanor after completing treatment. Proposition 133 would permit life sentences without parole for child sex trafficking. Amendment 81 would require state and local law enforcement to notify federal immigration authorities when a person whose immigration status cannot be verified is charged with a violent crime or has a prior felony conviction. Two amendments would change election and redistricting rules. Amendment 84 would require people voting by mail in state and federal elections to provide the last four digits of a Social Security number, a driver’s license number or a state-issued identification number. In-person voting procedures would not change. Amendment 86 would bar drawing congressional districts to benefit a political party and require approval from the state’s Independent Congressional Redistricting Commission for changes made outside the regular census cycle. Four measures address civil rights. Proposition 134 would require schools, colleges and universities to limit girls’ sports to biological females and boys’ sports to biological males. Current state law allows students to join teams consistent with their gender identity. Proposition 135 would prohibit gender-transition surgeries for minors when performed in response to a perceived gender identity, and bar insurers and state or federal programs from covering those procedures. Amendment 82 would establish a constitutional right to buy and sell natural gas in Colorado. Amendment 83 would establish a constitutional right to hunt and fish and name those activities as the preferred methods for managing wildlife populations. A final proposal, Amendment 85, would require ballot titles to be written at an eighth-grade reading level and prevent lawmakers from mandating wording that could interfere with that standard. The measures put decisions about taxation, public safety, election administration, energy and civil rights before voters on the same ballot. Their outcomes could affect state revenue and spending, law enforcement practices, and policies governing schools and public services.
