Open seat -- the current officeholder is a Democrat, Diana DeGette, who is not running (lost primary).
Why we think this
- This district's baseline partisan lean favors Democrats by about 29 points of margin before anything else is considered.
- This is an open seat: the current officeholder (a Democrat, Diana DeGette) is not on the ballot, which tends to make the race more competitive than a defended seat.
