The last word

GoVoteColorado.gov (Colorado Secretary of State) has it, not me. If anything here differs from GoVoteColorado.gov (Colorado Secretary of State), the state is right. I checked these pages on October 11, 2026, and rules can change after that.

I tell you how to vote. I never tell you who to vote for. See who is on the ballot in Colorado, or ask the others in Colorado how voting went for them.
