Anchored by Lewiston-Auburn, Maine's second-largest metro, Androscoggin spent decades as a Democratic stronghold built on organized labor before posting a Republican margin in 2024 — a realignment driven largely by working-class Catholic and Franco-American voters.
The Democratic margin in Androscoggin County has rarely exceeded sixty points in modern history; the Republican margin has rarely exceeded thirty-six points. 2024 delivered the county to the Republican candidate by six points.
Androscoggin County's demographics resemble the country more than they resemble most counties. A 88% non-Hispanic-white share, a 14% poverty rate, and a median household income of $67,873 — all within the broad national range. The county's voting pattern over the last decade is most similar to that of Kennebec County and Franklin County.
