With a 2024 presidential margin of D+24.4, this district ranks among the state's bluest, likely anchored by an urban core or dense college-adjacent population that consistently delivers lopsided margins across ballot levels.
Across the recorded series it reached a Democratic high of 46.1 points in 1964 and a Republican high of 48.7 points in 1896. Between 2020 and 2024 the district moved 6.2 points toward the Republican candidate; the 2024 margin was 24.4 points.
A population of 56,160, a 91% non-Hispanic-white share, and a median household income of $84,986 describe the district. The district's voting pattern over the last decade is most similar to that of State Senate District 15 and State Senate District 31.
