Denver County is both city and county, producing Democratic presidential margins above 50 points in recent cycles. Its dense, highly educated, and majority-minority electorate makes it the anchor of Colorado's statewide Democratic coalition.
The Democratic margin in Denver County has been steady. It reached its modern peak at sixty-one points in 2020; the 2024 margin was fifty-six points, still in line with the county's long pattern.
Denver County's political identity is inseparable from its demographic profile: a 59% non-Hispanic-white share, a median household income of $94,718, and the full diversity of a major metropolitan center. The county's voting pattern resembles other major urban centers most closely — Dane County and Multnomah County.
