Red River County, wedged between the Red River and Oklahoma border, returned an R+61.8 margin in 2024 — a spread typical of deep-rural East Texas counties where Democratic registration has eroded steadily over two decades.
The unraveling was not abrupt. The Democratic margin in Red River County peaked at ninety-one points in 1932; it narrowed steadily over the late twentieth century. The 2000 election delivered the county to the Republican party for the first time in many years, by a margin of fourteen points. By 2024, the margin had widened further.
The economic and demographic context is severe. Red River County's median household income of $48,491 is among the lowest of any county in the United States; 16% of residents live below the federal poverty line. The county's voting pattern over the last decade is most similar to that of Atoka County and Tyler County.
