Incumbent Republican Jeff Crank seeks reelection in Colorado's 5th District, a seat centered on Colorado Springs and historically Republican-leaning, where no Democrat has won. Democratic nominee Jessica Killin won her June 30 primary and released a July internal poll showing her within one point of Crank among likely voters, with notable undecideds. The race remains rated competitive by analysts, with traders assigning the Republican nominee a 65.5% implied probability driven by the district's partisan baseline, Crank's incumbency, and fundraising patterns. Key factors that could shift outcomes include turnout among military and suburban voters, any late-cycle national political environment, and additional public polling before November 3.
