Denver voters are officially on the clock. The city has started opening voter service and polling centers in phases ahead of the June 30 primary, giving residents a head start if they would rather not cut it close on Election Day. The main hub at Denver Public Library's Central Library opens Monday at 8 a.m., where in-person visitors can register to vote, request a replacement ballot, or cast a ballot on the spot, as long as they bring a valid ID.
Where and when to vote in person
According to the City and County of Denver, the Central Library serves as the primary Voter Service & Polling Center from Monday, June 15, through Thursday, June 18, open 8 a.m. to 5 p.m. Phase 1 sites, which include Barnum Recreation Center, Blair-Caldwell Library, and several other recreation centers, open Monday, June 22 at 8 a.m. and operate with extended hours through that week. Phase 2 locations come online Monday, June 29, with all centers offering voting from 7 a.m. to 7 p.m. on Election Day.
Drop boxes and how ballots are handled
If you prefer to skip the indoors altogether, all 24-hour ballot drop boxes opened June 8 and will stay available around the clock through Election Day, with city officials stressing that the receptacles are closely monitored. "The most popular way to vote is through one of our drop boxes," Denver Clerk and Recorder Paul López told Denver7. Election staff in bipartisan teams are responsible for emptying the boxes. López also cautioned unaffiliated voters that they will receive both a Republican and a Democratic ballot in the mail, and that filling out both will invalidate the vote; in the last primary, 612 of those double returns were canceled.
Deadlines and rules to keep in mind
The Colorado Secretary of State election calendar is blunt on one key point: ballots must be received by the county clerk by 7:00 p.m. on Election Day, June 30. Local guides and election officials highlight Monday, June 22, as the last safe day to put a ballot in the mail and the deadline to request a mailed replacement; after that, voters are urged to use an official drop box or vote in person, according to CPR News. If a mailed ballot comes back with a missing or mismatched signature, counties typically offer a short cure window so voters can fix the issue, but you will need to check your ballot status for specific instructions.
