Manny Rutinel holds a clear lead in the June 30 Democratic primary for Colorado's 8th Congressional District, reflecting his substantial fundraising advantage and endorsements from progressive groups such as BOLD PAC, while Shannon Bird trails with backing from moderate organizations including the Blue Dog Coalition and EMILY's List. Recent campaign developments include Rutinel's digital ads criticizing Bird's positions on immigration enforcement, sharpening differences between the liberal state representative and the former state lawmaker. Former Representative Yadira Caraveo and other early entrants have withdrawn, narrowing the contest to Rutinel, Bird, and lower-profile challengers. Traders appear to price in Rutinel's edge in resources and base mobilization for this open-seat primary in a closely divided district.
