Baker County's sparse high-desert ranching economy anchors one of the widest presidential margins in the state, with the 2024 gap exceeding 48 points despite a population under 17,000.
The Democratic margin in Baker County peaked at forty-five points in 1936. By 1968 the county had flipped, voting Republican for the first time in many years. The 2024 margin was forty-nine points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Baker County's median household income of $60,936 sits well below state and national norms, and 15% 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 Idaho County and Logan County.
