Colorado Democrats could be about to deliver another jolt to the party establishment. Longtime Rep. Diana DeGette faces one of the toughest primaries of her 27-year House career on Tuesday, as 29-year-old attorney and Democratic Socialist Melat Kiros mounts a well-funded challenge from the left. The contest is being watched as a test of whether last week's surprise progressive wins in New York were flukes—or the start of a pattern that puts veteran incumbents at risk. One House Democrat anonymously tells Axios they think it's "quite likely DeGette will lose," warning that party leaders ignore the race "at their own peril."

DeGette, a member of the Congressional Progressive Caucus and a Medicare for All supporter, is under fire from the left for taking corporate PAC money and backing Israel. She's supported by the CPC's PAC co-chairs and major abortion-rights groups, with pop-up PACs tied to establishment allies spending roughly $2 million on her behalf. Kiros was fired from a law firm after refusing to retract a pro-Palestinian post, and Mother Jones links Gaza policy directly to the surge on the far left. She's backed by Bernie Sanders, Ro Khanna, Justice Democrats, Democratic Socialists of America, and other left-wing groups. If she wins, Kiros has signaled she'll join a growing bloc of insurgents willing to condition support for party leaders on issues like corporate money and Israel policy.
