Middlesex County's large South Asian and Latino communities — centered in Edison, New Brunswick, and Piscataway — have made it a bellwether for how demographic shifts translate into durable partisan margins in New Jersey's suburbs.

The Democratic margin in Middlesex County has been steady. It reached its modern peak at forty-one points in 1964; the 2024 margin was eight points, still in line with the county's long pattern.

Middlesex County's political identity is inseparable from its demographic profile: a 41% non-Hispanic-white share, a median household income of $111,549, and the full diversity of a major metropolitan center. The county's voting pattern resembles other major urban centers most closely — South Central Connecticut Planning Region and Naugatuck Valley Planning Region.
