Colorado House District 40 anchors a densely populated urban corridor where the 2024 presidential margin of D+19 reflects a durable, lopsided alignment that has made the seat reliably uncompetitive at the top of the ticket.
Across the recorded series it reached a Democratic high of 73.2 points in 1896 and a Republican high of 46.7 points in 1892. Between 2020 and 2024 the district moved 5.8 points toward the Republican candidate; the 2024 margin was 19.0 points.
A population of 90,087, a 53% non-Hispanic-white share, and a median household income of $107,171 describe the district. The district's voting pattern over the last decade is most similar to that of State House District 41 and State House District 30.
