Wheeler County's roughly 1,500 residents make it one of the smallest electorates in Oregon, yet it consistently produces some of the state's widest presidential margins, reflecting the deep conservative lean of Oregon's high-desert ranching interior.
The Democratic margin in Wheeler County peaked at fifteen points in 1964. By 1980 the county had flipped, voting Republican for the first time in many years. The 2024 margin was forty-seven points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Wheeler County's median household income of $55,284 sits well below state and national norms, and 11% 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 Douglas County and Powell County.
