Swain County's unusual land profile — roughly 80% federally owned — shapes both its tax base and its economy, with Cherokee tourism and timber history defining a rural electorate that has leaned Republican by widening margins over the past decade.
The Republican margin in Swain County reached its widest at thirty points in 1972. The margin in 2024 was twenty-four points, in line with the county's deep historical pattern.
Swain County's loyalty is rooted in its place. Median household income of $52,349, a 60% non-Hispanic-white share, and a population of 14,013 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 Perry County and Saline County.
