Stretching from Boulder County through the ski-resort mountain towns, CO-2 delivered a 39.8-point Democratic presidential margin in 2024 — among the widest gaps of any competitive-state district in the West.

A population of 721,744, a 76% non-Hispanic-white share, and a median household income of $100,908 describe the district. The district's voting pattern over the last decade is most similar to that of Congressional District 1 and Congressional District 3.
The congressional 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.
