Manny Rutinel defeated Shannon Bird in the Democratic primary for Colorado's 8th Congressional District on June 30.
The 8th District was created following the 2020 census. Yadira Caraveo (D), the district's first representative, won election 48.4%-47.7% in 2022. Gabe Evans (R), the incumbent heading into the 2026 election, defeated Caraveo 49.0%-48.2% in 2024. Analysis surrounding the primary was set against the backdrop of the November 3 general election, specifically the chances of either the moderate Bird or the liberal Rutinel defeating Evans.
The Denver Post's John Aguilar wrote, "Democratic hopefuls in the race would be wise to restrain their most progressive impulses, said Robert Pruehs, a political science professor at Metropolitan State University of Denver. Elections in Colorado’s 8th District have very much turned on candidates successfully wooing independents, the district’s largest voting bloc [44% of voters]. ... [T]he Democratic candidates can stake out positions on the left up until the primary election. Then, in a district so evenly divided along partisan lines, they will need to artfully and nimbly steer to the political middle as November draws closer."
