Democratic socialist Melat Kiros beat U.S. Rep. Diana DeGette in a Colorado House primary Tuesday, a stunning victory for the first-time candidate against a nearly 30-year incumbent and another win for the Democratic Socialists of America.

Kiros, 29, is the latest candidate to rise from the party's left flank and boot an incumbent, with two self-described democratic socialists last week in New York. The Colorado district covers the dark blue city of Denver, and Kiros is expected to win in November and reach Congress in January.
