Lawrence County's R+64 margin in 2024 places it among the most one-sided counties in the state, a pattern consistent with the broader shift of rural, majority-white counties in the Arkansas Ozarks foothills toward supermajority Republican alignment over the past two decades.
The unraveling was not abrupt. The Democratic margin in Lawrence County peaked at eighty-one points in 1932; it narrowed steadily over the late twentieth century. The 2008 election delivered the county to the Republican party for the first time in many years, by a margin of twenty-one points. By 2024, the margin had widened further.
The economic and demographic context is severe. Lawrence County's median household income of $44,882 is among the lowest of any county in the United States; 20% of residents live below the federal poverty line. The county's voting pattern over the last decade is most similar to that of Randolph County and Poinsett County.
