Wheeler County's 2024 presidential margin of R+84.6 places it among the most one-sided counties in Texas, reflecting the deep-red alignment common to the sparsely populated ranching communities of the High Plains.
The unraveling was not abrupt. The Democratic margin in Wheeler County peaked at eighty-six points in 1932; 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 twenty points. By 2024, the margin had widened further.
The economic and demographic context is severe. Wheeler County's median household income of $60,167 is among the lowest of any county in the United States; 15% of residents live below the federal poverty line. The county's voting pattern over the last decade is most similar to that of Grant County and George County.
