For twenty-four years, Pemiscot County voted Democratic. Then it stopped.

Pemiscot County sits at the southernmost tip of Missouri's Bootheel, a region shaped by Mississippi Delta agriculture and persistent poverty. Its presidential margins have widened steadily over two decades, reflecting a rural realignment common across the mid-South.

The unraveling was not abrupt. The Democratic margin peaked at sixty-seven points in 1892 and narrowed across the late twentieth century. The 2004 election carried the county to the Republican party for the first time in many years, by zero points. Between 2020 and 2024 the county moved four points toward the Republican candidate; the 2024 margin was forty-nine points.

The economic context is severe: a median household income of $40,089 — among the lowest at this geographic scale — and a 30% poverty rate. The county's voting pattern over the last decade is most similar to that of Van Buren County and New Madrid County.
