Colonial Heights, one of Virginia's 38 independent cities, sits along the Appomattox River just south of Petersburg and has backed Republican presidential candidates by double digits in every cycle this century, with its 2024 margin reaching 32.5 points.
The Democratic margin in Colonial Heights city peaked at eight points in 1964. By 1968 the county had flipped, voting Republican for the first time in many years. The 2024 margin was thirty-two points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Colonial Heights city's median household income of $76,505 sits well below state and national norms, and 8% of residents live below the federal poverty line. The shift here is part of a broader realignment of working-class places across the country. The county's voting pattern over the last decade is most similar to that of Hanover County and Lexington County.
