With fewer than 3,000 residents spread across the Loup River watershed, Greeley County delivers outsized Republican margins—67-plus points in 2024—typical of Nebraska's rural agricultural interior where population has declined steadily for decades.
The Democratic margin in Greeley County peaked at fifty-four points in 1932. By 1980 the county had flipped, voting Republican for the first time in many years. The 2024 margin was sixty-eight points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Greeley County's median household income of $63,929 sits well below state and national norms, and 13% 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 Morton County and Howard County.
