Briscoe County's 1,790 residents make it among the least-populous counties in Texas, yet it consistently produces some of the state's widest presidential margins — the 2024 gap exceeded 79 points.
The unraveling was not abrupt. The Democratic margin in Briscoe County peaked at ninety-one points in 1932; it narrowed steadily over the late twentieth century. The 1996 election delivered the county to the Republican party for the first time in many years, by a margin of one points. By 2024, the margin had widened further.
The economic and demographic context is severe. Briscoe County's median household income of $45,417 is among the lowest of any county in the United States; 17% of residents live below the federal poverty line. The county's voting pattern over the last decade is most similar to that of Comanche County and Throckmorton County.
