Laclede County sits in the heart of the Missouri Ozarks, where a rural, predominantly white population has produced some of the state's most lopsided presidential results — the 2024 margin of R+66.8 reflects a regional shift decades in the making.
The Democratic margin in Laclede County peaked at seventeen points in 1932. By 1980 the county had flipped, voting Republican for the first time in many years. The 2024 margin was sixty-seven points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Laclede County's median household income of $53,282 sits well below state and national norms, and 18% of residents live below the federal poverty line. The shift here is part of a broader realignment of working-class places across the country. The county's voting pattern over the last decade is most similar to that of Wright County and Douglas County.
