Manny Rutinel leads the Democratic primary for Colorado's 8th Congressional District with strong fundraising exceeding $2.5 million and endorsements from progressive organizations including the Congressional Hispanic Caucus BOLD PAC. Shannon Bird follows with roughly $1.2 million raised and support from moderate groups such as Blue Dog PAC plus rural and agricultural backers. Yadira Caraveo, the former representative, withdrew earlier, narrowing the June 30 primary to a two-candidate contest. Recent digital ads from Rutinel's campaign targeting Bird's record on immigration enforcement have highlighted their ideological differences. These factors align with trader consensus favoring Rutinel's momentum in a swing district that will test the nominee against Republican incumbent Gabe Evans in November.
