State legislative officeholder from OpenStates nightly current-legislator data.
With a 2024 presidential margin of R+49.4, this district of nearly 1 million residents ranks among the most one-sided legislative constituencies in the state, leaving little competitive ground for statewide or local contests.
Across the recorded series it reached a Republican high of 36.7 points in 2012. Between 2020 and 2024 the district moved 6.5 points toward the Republican candidate; the 2024 margin was 18.4 points.
A population of 960,904, a 59% non-Hispanic-white share, and a median household income of $109,762 describe the district. The district's voting pattern over the last decade is most similar to that of State Senate District 30 and State Senate District 8.
The state-senate districts whose fingerprint — 2000–2024 trajectory, demographics, ancestry, religion — sits closest to this one, and why.
Twin score (0–100) = weighted cosine between tier-standardized fingerprints: presidential margins 2000–2024 with 12-yr trend and elasticity, ACS income, age, education, population and race, top reported ancestries, and religious adherence — chips name the closest-shared dimensions and the widest gap.
