A factual, nonpartisan field guide to what each measure would change, who is most directly affected, and where measures overlap. Start broad. Open a detailed guide when you want to go deeper.
How to read this site: categories are organizational—not endorsements, rankings, or claims about importance. “Most directly affected” tags identify the clearest first-order impacts; they are not exhaustive.
The ballot landscape
Some measures change constitutional rights. Others alter taxes, criminal penalties, election rules, or policies affecting schools and health care. The groupings below are designed to make those relationships visible.
Statewide measures
Constitutional amendments require 55% approval. Statutory propositions pass with a majority. Amendment 87 combines a constitutional amendment with statutory changes and also requires 55%.

Connections to notice
These pairings show shared policy terrain or direct legal interaction. They do not imply that the measures have the same sponsors, goals, or effects.
Amendment 87 would create graduated rates; Proposition 136 would cap individual and corporate income-tax rates at 4.4%. Because provisions conflict, affirmative vote totals matter if both pass.
Both can affect K–12 funding. Amendment 87 changes the income-tax structure and dedicates new revenue across education, health care, and child care; NN changes the state revenue limit to support K–12 investment.
One concerns buying and selling natural gas for heating and cooking. The other concerns hunting, fishing, and wildlife harvest. Both would add rights to the Colorado Constitution.
Both alter criminal penalties, but for different conduct: fentanyl-related offenses in Proposition 132 and human trafficking of a minor for sexual servitude in Proposition 133.
Proposition 134 concerns participation in school and collegiate sports; Proposition 135 concerns certain surgeries on minors and payment for those procedures.
Not statewide
The official 2026 Blue Book includes Ballot Issue 7A because it applies within the Front Range Passenger Rail District. Voters elsewhere in Colorado will not see it.
Would establish a 0.333% district sales and use tax and authorize debt to construct, operate, and maintain “Colorado Connector” passenger rail service along the Front Range, with specified tax exemptions and annual oversight.
Schematic—not county boundaries.
Method
The measure list, ballot numbering, and official ballot language are grounded in the Colorado Secretary of State’s certified 2026 list. The Colorado Legislative Council’s 2026 Blue Book is used as the primary neutral analysis source.
Card summaries are intentionally short. They describe the proposed legal change without telling voters how to vote. Expanded guides add fiscal analysis, historical context, visualizations, and documented arguments on multiple sides.
