Anchored in the Denver metro, this district's urban density and college-educated demographic profile have pushed presidential margins consistently past 15 points in recent cycles, making it one of Colorado's more reliably lopsided legislative seats.

A population of 164,250, a 75% non-Hispanic-white share, and a median household income of $111,924 describe the district. The district's voting pattern over the last decade is most similar to that of State Senate District 20 and State Senate District 16.
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.
