Morris County sits in the Piney Woods of northeast Texas, where a shrinking rural population and a decades-long partisan realignment have pushed its presidential margins past 50 points Republican in 2024.
The unraveling was not abrupt. The Democratic margin in Morris County peaked at ninety-four points in 1932; it narrowed steadily over the late twentieth century. The 2004 election delivered the county to the Republican party for the first time in many years, by a margin of seven points. By 2024, the margin had widened further.
The economic and demographic context is severe. Morris County's median household income of $58,645 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 St. Martin Parish and Okmulgee County.
