Clearfield County's R+51.5 margin in 2024 reflects a decades-long realignment in Pennsylvania's north-central coalfields, where a shrinking but older, rural white working-class electorate now votes at lopsided rates.
The Democratic margin in Clearfield County peaked at twenty-six points in 1964. By 1996 the county had flipped, voting Republican for the first time in many years. The 2024 margin was fifty-one points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Clearfield County's median household income of $62,152 sits well below state and national norms, and 15% 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 Caldwell County and Fleming County.
