Presidential and State Primaries Scheduling​

Consolidated Primaries: No

Colorado is one of the states that have not merged their presidential and state primaries. On a Presidential Election year, presidential primaries and State primaries are scheduled to run on different dates.

Following the passage of Propositions 107 & 108 in 2016, unaffiliated voters will receive a combined primary ballot and then may only vote in one party’s primary contest for each office. To qualify for the ballot Colorado holds closed party caucuses at which candidates who receive more than 30% of the vote proceed to the primary election.While each political party will still conduct caucus meetings, these meetings will not select presidential candidates.

Voting In Primaries​

  • Voters affiliated with a major party: may cast a ballot for candidates of the party they are affiliated with.
  • Voters affiliated with a minor party: if there is a minor party contest those affiliated with that minor party may cast a ballot for those candidates.
  • Unaffiliated voters: An unaffiliated voter may cast a ballot for any one political party. If an unaffiliated voter returns a ballot with more than one political party, the ballot will be rejected and none of the votes will be counted.

Delegates and Presidential Primaries​

The presidential primary process involves selecting delegates who will represent the state at the party's national convention. Delegates selected from the primary elections attend the party's national convention, where they officially nominate the presidential candidate. The candidate with the majority of delegates becomes the party's nominee for the presidential election.
