Lincoln County's 2024 presidential margin of R+61.2 places it among the most one-sided counties in a state that has shifted sharply toward Republican presidential candidates over the past two decades.
The Democratic margin in Lincoln County peaked at twenty-seven points in 1912. By 1980 the county had flipped, voting Republican for the first time in many years. The 2024 margin was sixty-one points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Lincoln County's median household income of $52,440 sits well below state and national norms, and 16% 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 Butler County and Todd County.
