Overview
- The June 30 Democratic primary in Colorado’s 1st District matches 29-year-old DSA‑aligned challenger Melat Kiros against 15‑term Rep. Diana DeGette in a race that national groups view as a test of the progressive insurgency.
- More than $1.5 million in late outside spending has supported DeGette through Pro‑Choice Majority Action and allied groups while additional AIPAC‑linked transfers and tech‑donor money flowed into other pro‑DeGette super PACs.
- Kiros has picked up endorsements from Sen. Bernie Sanders, the DSA and Justice Democrats and been helped by progressive organizing, while critics seized on her past Israel‑related comments and her refusal to label a deadly firebombing as antisemitic to drive attack ads.
- DeGette is defended by Colorado’s established Democratic delegation, labor and pro‑abortion groups that stress her seniority and committee influence as necessary to counter the Trump administration.
- Turnout and activist organization will decide the result because low‑turnout primaries let focused groups swing outcomes, and a Kiros victory would build on New York upsets to pressure party leaders on policy and nomination strategy.
