Jessica Killin is now the Democratic challenger to Republican incumbent Jeff Crank in Colorado's 5th Congressional District, and the race has already become one of the costliest in southern Colorado. Federal Election Commission data show more than $15 million has been spent in the contest, a figure that has climbed more than sevenfold from less than $2 million in 2024.
Killin, who has never held political office, won the Democratic nomination in June by defeating Joe Regan by 16,000 votes. She is running against a sitting member of Congress who beat Democratic challenger River Gassen by 50,000 votes in 2024, giving the race a built-in contrast: a first-time candidate trying to close a wide partisan gap in a district that has not often produced close congressional contests.
That is why Killin's name is drawing attention now. She and Crank both say affordability is the biggest issue facing people in El Paso County and southern Colorado, and both have tried to make that the center of their campaigns. Crank has said the focus should be on putting more money into the hands of the citizens of El Paso County, while Killin has cast the issue as a broader cost-of-living squeeze across the region.
But the fight over that message has been swallowed by negative advertising. Political ads have been running in every commercial break and mailers have been filling mailboxes, and both candidates have publicly objected to some of the attack ads that have defined the campaign. The result is a race that looks, on the ground, less like a debate about policy than a contest over who can survive the next wave of paid attacks.
Killin's campaign is leaning on polling that shows a dead heat heading into election night, but there is a catch: few polls have been published in CO-5, and most of the available ones were funded by her campaign or another Democratic organization. That makes the numbers useful as a snapshot, but not a clean read on the district, especially in a race where most of the money has gone into persuasion and attacks rather than public measurement.
What Killin has not yet fully answered is how she would turn her affordability pitch into policy. She has said she is focused on rolling up her sleeves, delivering results and giving voters something beyond partisanship, but the concrete plan for tackling the cost of living in southern Colorado remains the biggest open question in her campaign. Election night will show whether that message can overcome the spending flood and the district's recent history, or whether Crank keeps the seat and the Democratic challenge stalls again.
