Home to the University of Florida in Gainesville, Alachua County tilts heavily Democratic in a state that has trended Republican statewide — its 2024 presidential margin of D+21 reflects a college-town electorate unlike most of Florida.
The Democratic margin in Alachua County peaked at eighty-four points in 1892. By 1992 the county had flipped, voting Republican for the first time in many years. The 2024 margin was twenty-one points, the most Democratic-leaning result in the county's modern history.
The economic context is the key. Alachua County's median household income of $61,949 sits well below state and national norms, and 21% 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 Newport County and Solano County.
