San Francisco County returns Democratic presidential margins exceeding 60 points, reflecting a highly educated, dense electorate where registered Republicans account for a small single-digit share of voters.

The Democratic margin in San Francisco County has been steady. It reached its modern peak at seventy-five points in 2016; the 2024 margin was sixty-five points, still in line with the county's long pattern.

San Francisco County's political identity is inseparable from its demographic profile: a 39% non-Hispanic-white share, a median household income of $140,970, and the full diversity of a major metropolitan center. The county's voting pattern resembles other major urban centers most closely — Baltimore city and St. Louis city.
