Colorado’s NEW Presidential Primary- How to Participate (including 17-year-olds)

Colorado will hold its first Presidential Primary Election in two decades on March 3, 2020 – Super Tuesday! Political parties still hold party caucuses in March (check your local party website) and Colorado will still have a primary for statewide and local candidates in June. But ballots for the stand-alone Presidential Primary are mailed to voters beginning February 10. Here is what you need to know to participate:

  • Presidential primaries in Colorado are only held by the Democratic and Republican Parties. You must be registered as a Democrat, Republican, or Unaffiliated to participate.

  • Registered Democrats will receive only the Democratic Party ballot. Registered Republicans will receive only the Republican Party ballot.

  • Unaffiliated voters will be mailed both party ballots but can only vote and return one. Up until February 3, unaffiliated voters can also pre-designate their ballot preference, if they wish, by updating their voter registration. This will eliminate getting two ballots in the mail.

  • February 3 is the deadline to switch party affiliation to vote in a different primary.

  • ***NEW*** Voters who will turn 18-years-old by the General Election, Tuesday, November 3, 2020 – Can now VOTE in Primaries!

  • There is no registration deadline. You can register and vote up to and including Election Day.

If you have a Colorado Driver’s License or State ID, you can register to vote or check your registration at If you do not yet have a license or state ID, you can register by mail (downloadable form online at or in-person at any Boulder County Clerk & Recorder’s office (Boulder, Longmont, Lafayette). Youth can pre-register to vote as young as 16, however those who are ineligible to vote in 2020 cannot access their voter registration online after initially registering and must instead visit a Boulder County Clerk & Recorder office in-person to update or change their registration or submit a paper registration change.
