Colorado Democratic primary elections progressive vs establishment

Colorado's June 30, 2026 Democratic primaries feature a series of high-profile contests pitting progressive and DSA-backed challengers against veteran establishment incumbents, most notably DSA-backed Melat Kiros challenging 29-year incumbent Rep. Diana DeGette in Denver's 1st Congressional District. The races are being watched nationally as a follow-up to progressive victories in New York City the prior week, with millions of dollars in outside spending flooding key contests. The outcomes are seen as a bellwether for whether the Democratic Party's insurgent left wing can replicate its recent momentum in a new battleground state.
