Lucas County's small, aging population and deep rural character have pushed its presidential margins steadily rightward over two decades, reaching a 48-point Republican gap in 2024 — among the widest in the state.
The Democratic margin in Lucas County peaked at twenty-six points in 1964. By 2000 the county had flipped, voting Republican for the first time in many years. The 2024 margin was forty-eight points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Lucas County's median household income of $61,793 sits well below state and national norms, and 15% 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 Wayne County and Ringgold County.
