San Saba's 2024 presidential margin of R+78.8 ranks among Texas's most lopsided, reflecting a sparsely populated ranching economy where fewer than 6,200 residents anchor one of the state's least-contested electoral landscapes.
The unraveling was not abrupt. The Democratic margin in San Saba County peaked at eighty-eight points in 1932; it narrowed steadily over the late twentieth century. The 1992 election delivered the county to the Republican party for the first time in many years, by a margin of zero points. By 2024, the margin had widened further.
The economic and demographic context is severe. San Saba County's median household income of $55,819 is among the lowest of any county in the United States; 11% of residents live below the federal poverty line. The county's voting pattern over the last decade is most similar to that of Throckmorton County and Collingsworth County.
