Barry County, tucked into Missouri's southwestern Ozarks corner, recorded an R+63.5 presidential margin in 2024, placing it among the state's most heavily one-sided rural counties. Its small, predominantly white population has shifted sharply rightward over the past two decades.
The Democratic margin in Barry County peaked at eighteen points in 1912. By 1968 the county had flipped, voting Republican for the first time in many years. The 2024 margin was sixty-four points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Barry County's median household income of $58,346 sits well below state and national norms, and 15% 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 Laclede County and Lawrence County.
