Carroll County's R+61.6 margin in 2024 reflects a broader shift in rural west Tennessee toward lopsided Republican presidential tallies, a trend that has deepened steadily over the past two decades as the region's small-town and agricultural electorate realigned.
The Democratic margin in Carroll County peaked at sixteen points in 1976. By 2000 the county had flipped, voting Republican for the first time in many years. The 2024 margin was sixty-two points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Carroll County's median household income of $51,787 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 Morgan County and Meigs County.
