The results, reported Tuesday night, are still being finalized, but the breadth of the ballot reflects a state grappling with major policy questions simultaneously. Several measures would alter the state constitution, requiring 55% approval to pass, while others needed only a simple majority.

Among the most contentious were Amendment 81, which would require local law enforcement to communicate with federal Immigration and Customs Enforcement, overriding current state laws that ban the practice; Amendment 82, which would enshrine a right to buy and sell natural gas in the constitution, potentially undermining climate policies; and Amendment 83, which would guarantee hunting and fishing rights and make them the preferred means of wildlife management.

Voters also weighed Amendment 84, which would require mail ballot voters to provide the last four digits of their driver's license or Social Security number along with a signature; Amendment 85, which would require ballot questions to be written at an eighth-grade reading level; and Amendment 86, which would impose new restrictions on congressional redistricting in an effort to keep Colorado out of national gerrymandering fights.

On taxes, Amendment 87 proposed a graduated income tax, lowering rates for the least wealthy Coloradans and raising them for the wealthiest, while Proposition 136 would cap the income tax rate at the current 4.4%. Proposition NN would allow the state to retain revenue it already collects to increase K-12 funding, permanently raising the TABOR cap and directing surplus money to education programs for a decade. Proposition 137 would redirect sales tax revenue on sporting goods to conservation, reducing taxpayer refunds when the state exceeds its TABOR limit.

Criminal justice measures included Proposition 132, which would make possession of any amount of fentanyl a felony and increase penalties for unknowing possession, and Proposition 133, which would elevate child sex trafficking to a class 1 felony with a mandatory life sentence without parole.

Two propositions targeted transgender rights: Proposition 134 would require school sports participation based on a student's "biological reproductive system" and designate teams as male, female, or coed; Proposition 135 would prohibit certain surgeries on minors intended to alter biological sex characteristics and bar state and federal funding, Medicaid reimbursement, and insurance coverage for such procedures.

The election comes amid heightened national attention on Colorado's ballot process, which is known for its extensive use of citizen initiatives. With every statewide office also open this cycle, turnout was expected to be high, though final numbers were not immediately available.

Supporters of the various measures argued they would protect rights, improve clarity, or address pressing issues like fentanyl addiction and education funding. Opponents countered that several proposals, particularly those amending the constitution, could have unintended consequences or entrench policies that harm vulnerable communities.

For now, Colorado voters have spoken on a wide array of issues, and the results will shape state law and policy for years to come. Official tallies are expected to be certified in the coming weeks.
