Alcona's aging, rural population along Michigan's northeastern Lower Peninsula has produced some of the state's widest presidential margins, with the 2024 gap exceeding 40 points in a county of fewer than 12,000 residents.
The Democratic margin in Alcona County peaked at fifteen points in 1964. By 2000 the county had flipped, voting Republican for the first time in many years. The 2024 margin was forty-two points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Alcona County's median household income of $54,993 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 Montmorency County and Citrus County.
