Juneau's mix of state government workers, university employees, and a relatively diverse population anchors a D+25.8 margin that stands out sharply against Alaska's statewide Republican lean.
The Democratic margin in Juneau City and Borough reached its widest at forty-two points in 1964. The margin in 2024 was twenty-five points — still decisive.
Juneau City and Borough's loyalty is rooted in its place. Median household income of $101,661, a 63% non-Hispanic-white share, and a population of 31,794 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 Cook County and Williamsburg city.
