Somerset County's transformation tracks a broader pattern in affluent suburban New Jersey: college-educated voters shifted the presidential margin to D+13.9 in 2024, a reversal from its Republican-leaning baseline of the early 2000s.
The 2008 election was the turning point, when the Democratic candidate carried the county by six points. The 2024 margin was fourteen points, in line with the county's new direction.
The demographics suggest why. A population of 349,846, a 52% non-Hispanic-white share, and a median household income of $140,374 situate the county in the broader realignment patterns of recent cycles. The county's voting pattern over the last decade is most similar to that of Prince William County and Henrico County.
