Lawrence County's deindustrialized Rust Belt towns have shifted sharply rightward over two decades; its 2024 presidential margin of R+33.8 places it well outside Pennsylvania's statewide competitive range.
The Democratic margin in Lawrence County peaked at twenty-nine points in 1964. By 2004 the county had flipped, voting Republican for the first time in many years. The 2024 margin was thirty-four points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Lawrence County's median household income of $61,931 sits well below state and national norms, and 12% 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 Brooke County and Franklin County.
