Crane County's economy revolves around the Permian Basin oil patch, and its small, largely Hispanic population still delivered one of Texas's widest Republican presidential margins in 2024, reflecting a broader rightward shift in rural energy-producing counties.
The Democratic margin in Crane County peaked at ninety-two points in 1936. By 1972 the county had flipped, voting Republican for the first time in many years. The 2024 margin was seventy-three points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Crane County's median household income of $62,212 sits well below state and national norms, and 11% of residents live below the federal poverty line. The shift here is part of a broader realignment of working-class places across the country. The county's voting pattern over the last decade is most similar to that of Lea County and Reagan County.
