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.

The 2008 election was the turning point, when the Democratic candidate carried the district by thirteen points. The 2024 margin was twenty points, in line with the district's new direction.

The demographics suggest why. A population of 17,009, a 59% non-Hispanic-white share, and a median household income of $101,087 situate the district in the broader realignment patterns of recent cycles.
