Wrangell's roughly 2,100 residents, spread across an island community accessible mainly by sea or air, have backed Republican presidential candidates by wide margins, reflecting the resource-industry economy and geographic isolation common to rural Southeast Alaska.
The Democratic margin in Wrangell City and Borough peaked at seventy-eight points in 1964. By 1968 the county had flipped, voting Republican for the first time in many years. The 2024 margin was thirty-three points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Wrangell City and Borough's median household income of $63,750 sits well below state and national norms, and 12% of residents live below the federal poverty line. The shift here is part of a broader realignment of working-class places across the country. The county's voting pattern over the last decade is most similar to that of Fairbanks North Star Borough and Guadalupe County.
