Calhoun County's small, predominantly rural population has delivered Republican presidential margins above 45 points in each of the last several cycles, making it a reliable bellwether for the state's deep-red interior.
The unraveling was not abrupt. The Democratic margin in Calhoun County peaked at ninety-seven points in 1932; it narrowed steadily over the late twentieth century. The 1984 election delivered the county to the Republican party for the first time in many years, by a margin of thirty-four points. By 2024, the margin had widened further.
The economic and demographic context is severe. Calhoun County's median household income of $43,125 is among the lowest of any county in the United States; 20% of residents live below the federal poverty line. The county's voting pattern over the last decade is most similar to that of Cherokee County and Wythe County.
