For twenty-eight years, Poinsett County voted Democratic. Then it stopped.

Poinsett County sits in Arkansas's Mississippi Delta lowlands, where a shrinking, majority-white rural population has shifted its presidential margins rightward by roughly 40 points over the past two decades.

The unraveling was not abrupt. The Democratic margin peaked at eighty-eight points in 1932 and narrowed across the late twentieth century. The 2008 election carried the county to the Republican party for the first time in many years, by twenty-seven points. Between 2020 and 2024 the county moved four points toward the Republican candidate; the 2024 margin was sixty-four points.

The economic context is severe: a median household income of $46,707 — among the lowest at this geographic scale — and a 20% poverty rate. The county's voting pattern over the last decade is most similar to that of Lawrence County and Little River County.
