#DYK that 17 year-old voters that will be 18 years old by November 3, 2020 may register and are eligible to vote in the Colorado primaries? This law was passed by the Colorado General Assembly in 2019.

Colorado has a unique and nationally recognized voter-centric model for elections. For elections conducted by the County Clerk (Primaries, General, Presidential or odd-year coordinated November election), every active voter will receive their ballot by mail. Vote centers become available early and through election day for full voter services: registration, ballot replacement, accessible voting, etc. So the steps to vote are easy:

1. Register or update your voter registration.

2. Review your ballot.

3. Mail or drop off your ballot.
