Webster County delivered a 65-point Republican margin in 2024, reflecting the deep-red consolidation typical of sparsely populated Great Plains counties where agriculture and small-town demographics dominate the electorate.
The Democratic margin in Webster County peaked at thirty-eight points in 1892. By 1968 the county had flipped, voting Republican for the first time in many years. The 2024 margin was sixty-five points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Webster County's median household income of $64,347 sits well below state and national norms, and 10% 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 Slope County and Elk County.
