Tucked against the Idaho panhandle, Pend Oreille is one of Washington's least populous counties, with a rural, resource-economy identity that has produced Republican presidential margins exceeding 35 points in each of the last several cycles.
The Democratic margin in Pend Oreille County peaked at thirty-eight points in 1936. By 2000 the county had flipped, voting Republican for the first time in many years. The 2024 margin was thirty-nine points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Pend Oreille County's median household income of $67,436 sits well below state and national norms, and 14% 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 Mercer County and Shelby County.
