Suwannee County, anchored by Live Oak in Florida's rural interior, has shifted steadily toward supermajority Republican margins over the past two decades, reflecting a broader realignment across small, agricultural North Florida counties.
The unraveling was not abrupt. The Democratic margin in Suwannee County peaked at eighty-seven points in 1936; 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 thirty-seven points. By 2024, the margin had widened further.
The economic and demographic context is severe. Suwannee County's median household income of $56,658 is among the lowest of any county in the United States; 15% of residents live below the federal poverty line. The county's voting pattern over the last decade is most similar to that of Bradford County and Lafayette County.
