Coke County's sparse ranchland population of roughly 3,800 has delivered some of the widest presidential margins in west Texas, with 2024's R+79.6 result reflecting a pattern of near-unanimous rural consolidation seen across the Rolling Plains.
The unraveling was not abrupt. The Democratic margin in Coke County peaked at eighty-eight points in 1932; it narrowed steadily over the late twentieth century. The 1984 election delivered the county to the Republican party for the first time in many years, by a margin of thirty-three points. By 2024, the margin had widened further.
The economic and demographic context is severe. Coke County's median household income of $43,333 is among the lowest of any county in the United States; 23% of residents live below the federal poverty line. The county's voting pattern over the last decade is most similar to that of Hamilton County and Bosque County.
