Democratic socialist Melat Kiros defeats 15-term incumbent in Colorado House primary

Key Points:

• Melat Kiros, a 29-year-old democratic socialist, unseated long-serving Colorado US representative Diana DeGette in the Democratic primary for the state's 1st congressional district, securing a likely win in the November general election.
• Kiros, endorsed by Bernie Sanders and progressive groups like the Democratic Socialists of America and Justice Democrats, campaigned on a platform critical of US support for Israel, accusing it of genocide in Gaza and calling for an arms embargo.
• Kiros's victory follows a trend of progressive insurgents defeating established Democrats, reflecting growing voter support for younger candidates willing to challenge the party establishment and take strong stances on issues like corporate power, war, and immigration.
• The primary also saw anti-establishment sentiment in Colorado's gubernatorial race, with Attorney General Phil Weiser narrowly defeating Senator Michael Bennet, and progressive Manny Rutinel winning a competitive House primary to challenge vulnerable Republican incumbent Gave Evans.
• Incumbent Senator John Hickenlooper defeated a progressive primary challenger and will face Republican Mark Baisley in the general election, highlighting a mixed outcome for progressives in Colorado's recent primaries.
