Cumberland County's large active-duty and veteran population surrounding Fort Liberty shapes an electorate that has backed Democratic presidential candidates by double digits in recent cycles, while its diverse workforce keeps turnout competitive across party lines.
The Democratic margin in Cumberland County reached its widest at seventy-three points in 1936. The margin in 2024 was thirteen points — still decisive.
Cumberland County's loyalty is rooted in its place. Median household income of $61,291, a 42% non-Hispanic-white share, and a population of 338,545 together describe a community whose political habits are deeply settled. The county's voting pattern over the last decade is most similar to that of Sacramento County and Bernalillo County.
