Melat Kiros, a 29-year-old democratic socialist and first-time candidate, ousted Democratic Rep. Diana DeGette of Colorado in a primary challenge on Tuesday.
DeGette, a 15-term incumbent first elected in 1996, is the second member of Congress to lose her seat to a younger democratic socialist challenger after Darializa Avila Chevalier unseated Rep. Adriano Espaillait, the chair of the Congressional Hispanic Caucus, in New York’s 13th District last week.
