Presidential Primary Election, March 5, 2024
Presidential Primary elections are held in March in years in which a U.S. Presidential General Election will be held in November.  As with all elections in Colorado, presidential primary elections are conducted by mail ballot. Ballot content is finalized in January before the March election, and only presidential candidates are on the ballot for this election.  

In a presidential primary election, voters affiliated with a major party may cast a ballot for candidates of the party they are affiliated with. Unaffiliated voters may cast a ballot for candidates of any one political party.

There is not a voter registration deadline; voters can register and vote on the same day at any vote center, as long as they have lived in Colorado for 22 days prior to the election.  Refer to Primary Elections FAQs for information about presidential primary elections in Colorado.

Ballots for this election must be received no later than 7 p.m. on Election Day. Postmarks don't count!  Read below for more election information.
