About
Why this site exists
Clean voter rolls and informed voters make honest elections. This site is a project of True the Vote, pointing Colorado voters at the official tools that already exist — and at Scan Check Protect to verify your registration, and LegiTrack to follow the laws that govern it.
Elections in Colorado are run by the Colorado Secretary of State. Where anything here differs from what they publish, they are right and this page is not.
