Incumbent Republican Jeff Crank holds a clear edge in the Colorado 5th Congressional District race due to the seat’s longstanding Republican lean and his 2024 victory margin of roughly 14 points in a district that has never elected a Democrat. Jessica Killin, an Army veteran and former congressional chief of staff who won her June 2026 Democratic primary, has narrowed the gap through strong fundraising exceeding $2.7 million and national party support via the DCCC’s Red to Blue program, capitalizing on the district’s leftward demographic shifts in El Paso County. An internal July poll showed a statistical tie, and recent September attack ads from both sides have intensified the contest ahead of November 3 balloting. Forecasters rate the race Likely or Lean Republican, reflecting the underlying partisan baseline despite Killin’s competitive positioning among unaffiliated voters.
