Who can return ballots in the 2026 Colorado primary election?

Remember that anyone who is registered as a Republican or Democrat can return only their party’s ballot.

Unaffiliated voters may choose which of those ballots to return, but only one can be returned. If both are returned, neither will be counted.

Two other parties are holding primary elections, with the Libertarian ballot including just candidates for secretary of state and the Unity ballot including just candidates for governor. Those ballots can only be returned by party members.

Voters registered for a party without a primary will not receive a ballot.
