2026 Election Info

It is important to register to vote, keep your information up to date, and be on the lookout for your ballot the first week of October. Colorado offers same-day voter registration. If necessary, you can go to a vote center on the day of the election, register, and vote. However, it’s much easier to register ahead of time and get your ballot in the mail. Locations of vote centers and ballot drop off locations can be found here. In late September, sample ballots will be available here .

Important dates:

  • First week of October: Local ballots mailed, drop boxes open

  • Monday, October 19: Vote centers open

  • Monday, October 26: Last day to mail your ballot 

  • Tuesday, November 3: Election Day, last day to vote by 7 p.m.

The nonpartisan 2026 Blue Book is now available as a PDF online in English and en Español.
An audio version should also be available soon.
