Sherman County, anchored by the small city of Stratford, is a sparsely populated Texas Panhandle ranching community that recorded an R+88.1 presidential margin in 2024, placing it among the most one-sided counties in the state.
The unraveling was not abrupt. The Democratic margin in Sherman County peaked at eighty-nine points in 1936; it narrowed steadily over the late twentieth century. The 1980 election delivered the county to the Republican party for the first time in many years, by a margin of fifty-eight points. By 2024, the margin had widened further.
The economic and demographic context is severe. Sherman County's median household income of $61,250 is among the lowest of any county in the United States; 10% of residents live below the federal poverty line. The county's voting pattern over the last decade is most similar to that of Moore County and Sioux County.
