A 29-year-old democratic socialist with no corporate PAC money just knocked out a 15-term Democratic congresswoman — and outside groups spent $3 million trying to stop her.
Story Snapshot
- Melat Kiros defeated Rep. Diana DeGette in Colorado’s 1st Congressional District Democratic primary, ending DeGette’s nearly 30 years in Congress.
- Kiros ran on Medicare for All, universal childcare, and social housing while rejecting corporate PAC money and donations from the pro-Israel lobbying group known as the American Israel Public Affairs Committee (AIPAC).
- Outside groups spent a combined $3 million in the final month to protect DeGette — but it wasn’t enough.
- The upset is part of a growing national pattern of progressive insurgents toppling entrenched Democratic incumbents in safe seats.
An Upset That Shook the Democratic Establishment
Melat Kiros, a 29-year-old Ethiopian immigrant, attorney, and self-described democratic socialist, defeated Rep. Diana DeGette in Colorado’s 1st Congressional District primary. DeGette had held the seat since 1997 — nearly as long as Kiros has been alive. Kiros ran without corporate PAC money, backed instead by grassroots donors and progressive organizations like Justice Democrats. The win instantly became one of the most talked-about upsets of the 2026 primary season.
DeGette entered the race with a significant fundraising edge — more than $500,000 ahead of Kiros. Her campaign also had the backing of Super PACs that dropped $1.3 million in last-minute ads. When you add all outside spending, groups poured a combined $3 million into the race in just the final month to defend her seat. Despite that financial firepower, voters in one of Colorado’s most reliably Democratic districts chose the challenger.
What Kiros Ran On — and Against
Kiros built her campaign around policies she calls proven and cost-effective: Medicare for All, social housing, and universal childcare. She frames these not as radical ideas but as logical extensions of programs Americans already rely on. She also made corporate money a central issue, accusing DeGette of taking donations from pharmaceutical, energy, and defense industries and linking those donations to DeGette’s support for legislation like the 21st Century Cures Act.
Kiros explicitly refused money from AIPAC and positioned herself against what she calls corporate influence in foreign policy. She also drew controversy for describing the October 7, 2023 Hamas attack as an “inevitable consequence” of Israeli policies — a statement critics called inflammatory and unsupported. Her campaign also acknowledged she reposted a progressive ad containing derogatory language about Democrats, which was later removed. These moments gave opponents ammunition, but they didn’t stop her win.
Big Money Fought Back — and Lost
The race became a test case for whether establishment money could hold off a grassroots insurgency. A pop-up Super PAC ran aggressive ads against Kiros in the final weeks. DeGette’s supporters argued she had the experience and relationships needed to lead if Democrats retake Congress. They also pointed out that DeGette herself supports some progressive priorities, including Medicare for All and defunding Immigration and Customs Enforcement (ICE). But the argument didn’t land with enough primary voters.

The result reflects something both conservatives and liberals are noticing: voters on the left are just as fed up with career politicians as voters on the right. Whether you think Kiros’s platform goes too far or not far enough, the core message — that long-serving incumbents are more loyal to donors than to constituents — clearly resonated. That frustration isn’t partisan. It’s the same anger driving challenges across the political spectrum against a political class that many Americans believe has stopped working for them.
A National Pattern, Not a One-Off
This race fits a well-documented trend. Since 2016, progressive groups have systematically targeted Democratic incumbents in safe seats. In 2025, Democratic National Committee Vice Chair David Hogg announced a $20 million initiative specifically to fund primary challenges against sitting Democrats in uncompetitive districts. Colorado’s 1st District — a seat with no serious Republican challenger — was exactly the kind of race that movement had in mind. Kiros’s win shows the strategy can work.
The broader question now is what this means for the Democratic Party heading into the general election. Kiros will almost certainly win in November in this heavily Democratic district. But her victory adds another voice to the party’s growing internal debate over identity, money, and who the party actually represents. For voters on both sides who believe the political establishment protects itself first, this race offered a rare example of that system losing — at least for one night in Colorado.
