American congresswoman; Colorado’s 1st district since 1997
Progressive candidates backed by aligned groups have won key Democratic primaries in New York and Colorado, challenging incumbents seen as pro-Israel. The wins reflect a broader shift in the party as several pro-Israel incumbents face tough primary fights amid debates over Gaza policy and foreign money in politics.
In Colorado, progressive challengers have surged in major primaries, ousting long‑standing incumbents in Denver and sweeping other contests. Melat Kiros has defeated Diana DeGette for the Democratic nomination in Colorado’s 1st District, while Phil Weiser has defeated Michael Bennet for the gubernatorial nomination. Other races show momentum for insurgent candidates and a continued leftward shift within the state Democratic establishment.
