Montour County, anchored by the small city of Danville, has shifted markedly rightward over the past two decades. In 2024 it backed the Republican presidential candidate by 21 points, reflecting broader rural consolidation across central Pennsylvania.
The Republican margin in Montour County reached its widest at forty-four points in 1928. The margin in 2024 was twenty-one points, in line with the county's deep historical pattern.
Montour County's loyalty is rooted in its place. Median household income of $76,976, a 90% non-Hispanic-white share, and a population of 18,103 together describe a community whose political habits are deeply settled. The county's voting pattern over the last decade is most similar to that of Bartholomew County and Washington County.
