Danville, a former textile hub on the North Carolina border, has shifted decisively toward Democrats over the past two decades as its population has grown majority-Black and its manufacturing base has contracted.
The 2004 election was the turning point, when the Democratic candidate carried the county by zero points. The 2024 margin was twenty-one points, in line with the county's new direction.
The demographics suggest why. A population of 42,214, a 40% non-Hispanic-white share, and a median household income of $44,423 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 Charles County and Manassas Park city.
