With races from Congress to local offices, this article explains how candidates in Colorado qualify for the ballot through caucuses, assemblies, and petition drives under state election law. The process varies for major party candidates, third-party candidates, and ballot initiatives, with specific signature requirements and voting thresholds at each stage.

Why it matters

Understanding the ballot access process is crucial for voters to know which candidates and issues will appear on their ballots, as well as the factors that shape the choices available in an election. This knowledge empowers citizens to participate more fully in the democratic process.

The details

In Colorado, the process for getting on the ballot begins with precinct-level caucuses where attendees can nominate candidates. Delegates are then selected proportionally based on the caucus votes. These delegates then attend county, district, and state assemblies where candidates need to reach a 30% vote threshold to secure a spot on the primary ballot. As an alternative, candidates can also petition to get on the ballot by collecting a minimum number of signatures, which varies by office. This multi-step process aims to balance grassroots participation with party control over nominations.

  • Precinct caucuses were held on April 1, 2026.
  • County, district, and state assemblies will be completed by April 11, 2026.
  • The primary election is scheduled for June 2026.
