Prowers County, anchored by Lamar on the Arkansas River, has delivered Republican presidential margins exceeding 50 points in recent cycles, making it among the most reliably one-sided counties in a state that otherwise trends competitive statewide.
The Democratic margin in Prowers County peaked at twenty-nine points in 1964. By 1980 the county had flipped, voting Republican for the first time in many years. The 2024 margin was fifty-one points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Prowers County's median household income of $53,508 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 Gem County and Gooding County.
