Delta County's roughly 5,300 residents make it among the smallest in Texas by population, yet its presidential margins have grown steadily lopsided — the 2024 gap of nearly 70 points reflects a broader rural realignment across Northeast Texas.
The unraveling was not abrupt. The Democratic margin in Delta County peaked at ninety-two 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 twenty-two points. By 2024, the margin had widened further.
The economic and demographic context is severe. Delta County's median household income of $66,575 is among the lowest of any county in the United States; 11% of residents live below the federal poverty line. The county's voting pattern over the last decade is most similar to that of Burleson County and Jasper County.
