Don’t miss your opportunity to participate in Colorado’s Presidential Primary! Voting is happening now through March 5. Here's what you need to know.

Quick tips

  • Registered Democrats vote in the Democratic Primary.
  • Registered Republicans vote in the Republican Primary.
  • Unaffiliated voters may vote in either party’s primary but may only vote in one primary.
  • Colorado is an all-options state. Registered voters are mailed ballots, which they can vote and return; alternately, any voter can choose to vote in person at a vote center (see details below).
  • It is never too late to register to vote—you may register to vote up to and including Election Day!

Return your mail ballot

Do not mail your ballot back after Feb 26. Instead, it is recommended to drop your ballot off at a ballot dropbox, such as the one outside of the UMC (located on the sidewalk leading up to the Southside Terrace on Euclid Avenue) before 7 p.m. Tuesday. 

Not a Boulder County ballot? No problem—any Colorado voter can use any dropbox in the state to return their mail ballot. Find other dropbox locations in Boulder County.

Vote in person

If you haven't received your mail ballot or haven’t registered to vote yet, you will need to vote in person. Because the primary ballot is the same statewide, any voter from any Colorado county can vote in person at the UMC for this election.

Find off-campus vote center and dropbox locations. Don’t forget to bring valid ID, such as your Buff OneCard or Colorado driver’s license/ID; see other ID options.

If you are a student and have questions regarding registration, please visit Boulder County’s student voting guidelines.
