Lawrence, a rural county anchored by Lawrenceburg along the Alabama border, recorded a 69-point Republican presidential margin in 2024 — among the widest gaps in a state already dominated by one-party results at the county level.
The Democratic margin in Lawrence County peaked at thirty-five points in 1940. By 2000 the county had flipped, voting Republican for the first time in many years. The 2024 margin was sixty-nine 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 $54,706 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 McNairy County and Union County.
