Anchored in the greater Portland area, this district backed the 2024 Democratic presidential nominee by nearly 19 points — a margin that places it well outside the state's competitive middle and reflects the region's younger, college-educated electorate.
Across the recorded series it reached a Democratic high of 28.9 points in 1912 and a Republican high of 71.4 points in 1956. Between 2020 and 2024 the district moved 0.6 points toward the Democratic candidate; the 2024 margin was 8.3 points.
A population of 37,736, a 94% non-Hispanic-white share, and a median household income of $74,893 describe the district. The district's voting pattern over the last decade is most similar to that of State Senate District 24 and State Senate District 11.
