Colorado Begins Mailing Primary Ballots as Denver Adds 24‑Hour Drop Box

Expanded secure return options with targeted outreach aim to boost low primary turnout, ensuring ballots reach county clerks by the June 30 deadline.

Overview

County offices have started sending mail ballots to registered Colorado voters to launch the primary voting window.
Denver unveiled a 24-hour ballot drop box at Athmar Park Branch Library, bringing the county total to 48 permanent drop boxes.
Election officials say all primary ballots must be received by the county clerk by 7 p.m. on June 30 and not just postmarked.
Clerk and Recorder Paul Lpez said drop boxes are monitored around the clock and are emptied by bipartisan teams to protect integrity.
Local leaders and the Denver Public Library are promoting the new drop box and outreach in low-turnout neighborhoods to raise primary participation.
