Over 700,000 Coloradans have already cast their ballots in the 2025 election. If you’re eligible to vote, it’s not too late to join them.

Election Day is Tuesday. Voters who have already received a mail ballot must place it in a drop box or return it to an in-person polling location 7 p.m. Tuesday for their votes to be counted. It’s too late to return a ballot by mailing it.

Colorado has same-day voter registration, meaning that any eligible voter, even if they are not yet registered, can still cast a vote in the 2025 election by visiting an in-person polling location before 7 p.m. on Election Day.

Information about ballot drop box and in-person service locations can be found at GoVoteColorado.com and on local county clerks’ websites.

Data released by the secretary of state’s office showed that 700,103 Colorado voters had returned their ballots as of Friday. As a percentage of active registered voters, that’s a higher figure than was reported at the same point in the past two off-year election cycles, putting the state on track for its highest turnout in an off-year election since 2019.

As usual, older Coloradans have made up the vast majority of voters returning a ballot so far this year, with voters under age 55 accounting for less than a third of all ballots returned as of Friday. Registered Republicans have returned slightly more ballots (204,332) than registered Democrats (202,432), but both trail behind the 285,175 ballots returned by unaffiliated voters, who make up half of all registered voters in the state.

What’s on the ballot

Colorado holds coordinated elections in odd-numbered years to elect candidates for certain school boards, municipal offices and other local races, often alongside one or more statewide ballot issues.

In 2025, Colorado lawmakers have referred two measures to the ballot, Propositions LL and MM, which would shore up funding for the state’s universal school meals program. Detailed information about both ballot measures is available in the 2025 Blue Book, prepared by nonpartisan state fiscal analysts.

Dozens of public school districts across the state are holding elections for their boards of education, drawing millions of dollars in outside spending by pro-charter-school organizations, conservative groups and teachers unions.

Municipalities including Denver, Aurora, Lakewood, Fort Collins and Pueblo are also holding elections featuring city council and mayoral races and local ballot issues.

Checking the status of your ballot

Colorado’s BallotTrax service allows voters to monitor the status of their mail ballot via phone, email or text notifications. Voters can also check the status of their ballot at any time by entering their registration information on the secretary of state’s website.

On average, about 1 percent to 2 percent of mail ballots in each election in Colorado are rejected because of a signature discrepancy or other issue. Voters whose ballots are rejected should receive a BallotTrax notification or a letter from their county elections office, which will include the steps they need to take to “cure” the problem and ensure their ballot is counted.
