Buncombe's D+24.7 margin in 2024 stands out sharply against the surrounding mountain counties, driven by Asheville's urban core and an influx of college-educated migrants that has steadily widened the Democratic advantage over the past decade.
The Democratic margin in Buncombe County reached its widest at fifty points in 1912. The margin in 2024 was twenty-five points — still decisive.
Buncombe County's loyalty is rooted in its place. Median household income of $74,436, a 82% non-Hispanic-white share, and a population of 274,360 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 Wake County and Baltimore County.
