Crawford County's R+39.3 margin in 2024 reflects a broader rural realignment in Pennsylvania's northwest corner, where manufacturing decline and an aging population have steadily shifted a once-competitive county toward lopsided results.
The Democratic margin in Crawford County peaked at twenty-six points in 1964. By 1968 the county had flipped, voting Republican for the first time in many years. The 2024 margin was thirty-nine points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Crawford County's median household income of $60,476 sits well below state and national norms, and 14% 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 Washington County and Wadena County.
