This sparsely populated county in the Ouachita Mountains delivered a 72.5-point Republican margin in 2024, reflecting a rural southeastern Oklahoma electorate that has shifted decisively rightward over the past two decades despite its historically Democratic roots.
The unraveling was not abrupt. The Democratic margin in Pushmataha County peaked at seventy-five points in 1932; it narrowed steadily over the late twentieth century. The 2000 election delivered the county to the Republican party for the first time in many years, by a margin of eight points. By 2024, the margin had widened further.
The economic and demographic context is severe. Pushmataha County's median household income of $47,940 is among the lowest of any county in the United States; 21% of residents live below the federal poverty line. The county's voting pattern over the last decade is most similar to that of Johnston County and Love County.
