Winn Parish, birthplace of Huey Long, sits in Louisiana's rural north-central hills and has shifted decisively toward Republican presidential candidates over the past two decades, recording a 54-point margin in 2024.
The unraveling was not abrupt. The Democratic margin in Winn Parish peaked at ninety-five points in 1932; it narrowed steadily over the late twentieth century. The 2000 election delivered the county to the Republican party for the first time in many years, by a margin of twenty-nine points. By 2024, the margin had widened further.
The economic and demographic context is severe. Winn Parish's median household income of $48,871 is among the lowest of any county in the United States; 24% of residents live below the federal poverty line. The county's voting pattern over the last decade is most similar to that of Iberia Parish and Jackson Parish.
