Tucked against the Oregon border and home to Redwood National Park, Del Norte combines a small timber-economy population with rural voter patterns that have produced Republican presidential margins exceeding 15 points in recent cycles.
The Republican margin in Del Norte County reached its widest at forty-one points in 1924. The margin in 2024 was sixteen points, in line with the county's deep historical pattern.
Del Norte County's loyalty is rooted in its place. Median household income of $67,058, a 64% non-Hispanic-white share, and a population of 27,107 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 Houghton County and Ferry County.
