Stevens County, a largely rural expanse in northeastern Washington bordering Idaho and Canada, recorded an R+43.9 presidential margin in 2024 — among the widest in a state that overall tilts heavily Democratic.
The Democratic margin in Stevens County peaked at sixty-two points in 1896. By 1968 the county had flipped, voting Republican for the first time in many years. The 2024 margin was forty-four points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Stevens County's median household income of $69,327 sits well below state and national norms, and 12% 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 Bowman County and Sedgwick County.
