Melat Kiros, a progressive upstart, achieved a significant upset by defeating 15-time incumbent U.S. Rep. Diana DeGette in Colorado's 1st Congressional District Democratic primary. This victory, reported by the AP, secures Kiros the Democratic nomination. The 29-year-old's success demonstrates that anti-establishment wins seen in New York City can be replicated elsewhere, potentially alarming other Democratic incumbents. Given the district's strong Democratic lean, Kiros is poised to become the first Black woman to represent Colorado in Congress and only the third woman to represent the district since 1972. The Associated Press called the race for Kiros after she led DeGette by 6 points. Despite DeGette's substantial financial advantage, fueled by over $1.5 million from Pro-Choice Majority Action, Kiros prevailed. Kiros received significant backing from left-leaning groups like Justice Democrats, who spent over $500,000, and American Priorities. She also garnered a major endorsement from Sen. Bernie Sanders, while DeGette faced criticism from the left for her stance on Israel and corporate PAC support. Kiros now advances to the November 3 general election, where she is the presumptive winner in the heavily Democratic district encompassing Denver and parts of Arapahoe County.
