# A 29-Year-Old Insurgent Ousts 15-Term Rep. Diana DeGette in Denver Primary

Melat Kiros, a 29-year-old democratic socialist, defeated Rep. Diana DeGette in Colorado's Democratic primary for the Denver-area U.S. House seat — ending one of the longest congressional tenures in the state and delivering the latest jolt to the party's establishment.

One of Colorado's longest-serving members of Congress has been unseated in her own party's primary, in an upset that underscores the restless mood on the Democratic left.

## The result

Melat Kiros, 29, defeated Rep. Diana DeGette in the June 30 Democratic primary for Colorado's 1st Congressional District, which covers Denver and its inner suburbs, [the Colorado Sun reported](https://coloradosun.com/2026/06/30/colorado-primary-election-diana-degette-melat-kiros-results/). Kiros won by roughly six points, according to the Sun's count. DeGette, 68, had held the seat since 1996 — 15 terms — and was the senior Democrat on the House health subcommittee, with a hand in writing the Affordable Care Act.

"Denver voters sent a clear message," Kiros said on election night, according to the Sun, casting the win as a generational break with the party's old guard.

## Who Kiros is

Kiros, whose family immigrated from Ethiopia when she was an infant, is a former attorney who more recently worked as a barista while pursuing a graduate degree in public policy, the Sun reported. A democratic socialist, she campaigned on Medicare for All, abolishing Immigration and Customs Enforcement, and curbing corporate money in politics — a platform aimed squarely at younger, left-leaning voters.

## The fault lines

The sharpest divide between the candidates was over U.S. policy toward Israel. Kiros opposes all military aid to Israel and has said the country is committing genocide in Gaza; DeGette supported defensive but not offensive aid and, the Sun reported, accused Kiros of antisemitism over her handling of a 2025 firebombing in Boulder. The clash mirrored a broader generational and ideological rift within the party. A third candidate, University of Colorado regent Wanda James, finished well back.

Kiros was outspent by outside groups aligned with DeGette — including more than $1.5 million from an abortion-rights super PAC — but drew roughly half a million dollars in support from Justice Democrats, the progressive group known for backing primary challenges to incumbents, according to the Sun.

## What's next

Because the Denver-based district has not elected a Republican since 1970, the primary winner is the heavy favorite in November, when Kiros is set to face a Republican nominee. Her victory adds to a run of insurgent wins on the Democratic left driven by frustration over Gaza, the cost of living and the sense that entrenched incumbents have lost touch — a dynamic party leaders will be watching closely as the midterms approach. Not every voter was persuaded; one DeGette supporter, quoted by the Sun, dismissed the appetite for change as "a bunch of hot air." But the result speaks for itself.
