Despite its small-town, agricultural character — traits that trend Republican elsewhere in New England — Caledonia County delivered a 12-point Democratic margin in 2024, reflecting Vermont's broader departure from rural voting patterns seen nationally.
The Democratic margin in Caledonia County reached its widest at twenty-eight points in 1964. The margin in 2024 was twelve points — still decisive.
Caledonia County's loyalty is rooted in its place. Median household income of $69,970, a 93% non-Hispanic-white share, and a population of 30,475 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 Lincoln County and Grafton County.
