Ogemaw, a lightly populated county in Michigan's Lower Peninsula, delivered a 42-point Republican presidential margin in 2024 — among the widest in the state — reflecting the region's predominantly rural, non-college white demographic profile.
The Democratic margin in Ogemaw County peaked at twenty-seven points in 1964. By 2012 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. Ogemaw County's median household income of $54,666 sits well below state and national norms, and 17% 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 Arenac County and Gladwin County.
