Montmorency County, a sparsely populated stretch of northern Lower Peninsula forest, recorded an R+45.3 presidential margin in 2024—among the widest in a state otherwise defined by competitive statewide races.
The Democratic margin in Montmorency County peaked at twenty-three points in 1964. By 2000 the county had flipped, voting Republican for the first time in many years. The 2024 margin was forty-five points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Montmorency County's median household income of $49,756 sits well below state and national norms, and 18% 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 Kalkaska County and Oscoda County.
