Registered voters in Colorado should have received their ballots in the mail for the June 25 primary, which includes races for Congress, the state Legislature, the University of Colorado Board of Regents and other local positions.

Voters can contact their county clerk if they have not received their ballot or check the online BallotTrax system. They can also visit the secretary of state’s website to make a plan to vote in person ahead of or on Election Day. Ballots need to be received by the county clerk by 7 p.m. on that day, so voters should make a plan to mail their ballot at least eight days ahead of time or drop it off in person.

In a primary election, same-party candidates compete to advance as their party’s candidate in the general election in November. In Colorado, registered Republican voters cast ballots in the Republican primaries, Democratic voters cast ballots in the Democratic primaries, and unaffiliated voters cast Republican or Democratic ballots, but not both.
