Colorado’s presidential primary ballots start dropping this week. Here’s what you need to know.


Colorado’s presidential primary ballots began going out to voters Monday.

Close to two dozen candidates — six Republicans and 17 Democrats — will appear on their respective party’s ballots, including several who dropped out too late to have their names removed.

Colorado voters who have registered as either Democrats or Republicans will receive primary ballots for only their affiliated party. Unaffiliated voters, who comprise a plurality of the state’s voter base, will receive ballots for both parties but can only return one.

Ballots will be due back March 3, which is known as Super Tuesday because more than a dozen states hold primaries then. This will be Colorado’s first year holding a primary on Super Tuesday after several cycles with caucuses.

To make the primary ballot, candidates had the option of filing petitions with 5,000 signatures from voters or simply paying a $500 filing fee with a notarized statement of intent. The filing deadline was Dec. 9, and several who qualified for Colorado’s ballot have already exited the race: Democrats Michael Bennet, Cory Booker, John Delaney, Marianne Williamson and Andrew Yang and the Republican talk radio host Joe Walsh.

The ballots voters will receive in the mail in the coming days will include no races other than the presidential contest. Other primary races, including for Colorado’s congressional and statehouse seats, will be decided in a June 30 election.

Colorado residents who will be 18 years old by the Nov. 3 election may register to vote in the March 3 primary up to or on that day. For more information, visit the Colorado Secretary of State’s Office website at or that of your county clerk and recorder.
