Swisher County, anchored by the small city of Tulia, has voted Republican in presidential races by margins exceeding 60 points in recent cycles, reflecting the broader political consolidation of rural, agricultural West Texas.
The unraveling was not abrupt. The Democratic margin in Swisher County peaked at eighty-two points in 1936; 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 thirty points. By 2024, the margin had widened further.
The economic and demographic context is severe. Swisher County's median household income of $36,165 is among the lowest of any county in the United States; 30% of residents live below the federal poverty line. The county's voting pattern over the last decade is most similar to that of Dickens County and Burleson County.
