Multnomah County, anchored by Portland, delivered a 61.6-point Democratic margin in 2024, making it one of the most lopsided urban counties in the West. High population density and a young, college-educated workforce drive its outsized tilt.

The Democratic margin in Multnomah County has been steady. It reached its modern peak at sixty-two points in 2024; the 2024 margin was sixty-two points, still in line with the county's long pattern.

Multnomah County's political identity is inseparable from its demographic profile: a 68% non-Hispanic-white share, a median household income of $88,766, and the full diversity of a major metropolitan center. The county's voting pattern resembles other major urban centers most closely — Dane County and Denver County.
