Lafayette County's rural, timber-economy character and sparse population of roughly 7,000 have produced some of the most lopsided presidential results in Florida, with Republican margins routinely exceeding 70 points.
The unraveling was not abrupt. The Democratic margin in Lafayette County peaked at ninety-four points in 1932; it narrowed steadily over the late twentieth century. The 1984 election delivered the county to the Republican party for the first time in many years, by a margin of twenty-seven points. By 2024, the margin had widened further.
The economic and demographic context is severe. Lafayette County's median household income of $62,757 is among the lowest of any county in the United States; 18% of residents live below the federal poverty line. The county's voting pattern over the last decade is most similar to that of Appling County and Covington County.
