Fulton County sits at the southern edge of the Adirondacks, and its small-city and rural mix has delivered some of the widest Republican presidential margins in upstate New York over the past decade.
The Democratic margin in Fulton County peaked at thirty-seven points in 1964. By 2000 the county had flipped, voting Republican for the first time in many years. The 2024 margin was thirty-six points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Fulton County's median household income of $66,533 sits well below state and national norms, and 13% 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 Dodge County and Herkimer County.
