Louisiana 31st State Senate District sits in the Gulf South. For most of the post-war period it was a Democratic district — its working-class profile gave it the same political habits as much of its region. That identity has shifted decisively in the last twenty years.
The Democratic margin in Louisiana 31st State Senate District peaked at ninety-four points in 1916. By 2000 the district had flipped, voting Republican for the first time in many years. The 2024 margin was thirty-two points, the most Republican-leaning result in the district's modern history.
The economic context is the key. The median household income of $49,123 sits well below state and national norms, and 23% of residents live below the federal poverty line. The shift here is part of a broader realignment of working-class places across the country.
