Six House members have already been denied renomination this cycle, and next week’s Colorado primary could add another to the list.
Rep. Diana DeGette (D-Denver) is facing a serious challenge from attorney and Democratic Socialist Melat Kiros in a race that pegs a far left liberal against a traditional liberal incumbent. Congresswoman DeGette has been in office since winning her first term in 1996, ironically a year before her opponent was born.
The June 23 New York primary underscored the strength of the Democratic Socialist candidates. Three DSA‑aligned contenders won congressional primaries in New York City, victories that all but assure them seats in November. Two of the winners defeated incumbents: Reps. Dan Goldman and Adriano Espaillat. In Brooklyn, state Assemblywoman Claire Valdez easily won a crowded primary to succeed retiring Rep. Nydia Velázquez (D).
In both the Goldman and Espaillat races, the challengers overcame major financial disadvantages. Brad Lander, the former NYC Comptroller, defeated Rep. Goldman despite being outspent 7:1; Goldman spent more than $7 million attempting to hold his seat but lost 66-34 percent. Darializa Avila Chevalier edged Rep. Espaillat 49-46 percent, despite a 2:1 spending deficit.
Earlier in the year, three additional incumbents, Reps. Dan Crenshaw (R‑TX), Al Green (D‑TX), and Thomas Massie (R‑KY), were defeated by wide margins. A sixth incumbent loss stemmed from redistricting rather than voter rejection.
In Texas’ newly drawn 33rd District, former Congressman and 2024 Senate nominee Colin Allred defeated freshman Rep. Julie Johnson (D‑Farmers Branch). Although the district lies entirely within Dallas County, most of its territory was unfamiliar to Johnson and markedly different from her original 32nd District, which was transformed into a Republican‑leaning seat stretching into East Texas.
These results reflect a broader frustration within both party bases and recent signs suggest that Colorado Democrats may be experiencing similar tensions.
Rep. DeGette’s vulnerability became apparent when she barely qualified for the ballot at the 1st District nominating convention. Colorado candidates must either secure 30 percent of convention delegate support or submit sufficient petition signatures to earn a ballot position. Rep. DeGette cleared the 30 percent threshold by just eight votes in an official intra-party caucus where delegates overwhelmingly backed Kiros.
A reported Data for Progress Colorado poll showed Kiros leading next week’s 1st District race with 41 percent, followed by DeGette at 36 percent and University of Colorado Regent Wanda James at six percent. Like Chevalier in New York, Kiros is a strong anti‑Israel activist, reflecting issues increasingly becoming prominent in Democratic primaries.
Money favors Rep. DeGette, and has been bolstered by significant outside spending. However, as seen in other incumbent defeats, financial advantages have not always been enough to counteract shifting voter sentiment.
Additional signs of political turbulence for Colorado incumbents appear in the gubernatorial and Senate primaries.
Recent polling indicates a tightening race in the open Democratic gubernatorial primary. Sen. Michael Bennet (D) faces a strong challenge from Attorney General Phil Weiser, who has mounted an unexpectedly competitive campaign effort.
A late May Colorado Community Research poll (May 22-26; 796 likely Democratic primary voters) showed Weiser leading Sen. Bennet 41-34 percent. A follow‑up Public Policy Polling survey (June 1-2; 505 likely Democratic primary voters; text & live interview) found Bennet rebounding but to only a tenuous 36-30 percent.
The Colorado Community Research poll also tested the US Senate primary and surprisingly found Sen. John Hickenlooper leading state Sen. Julie Gonzalez (D‑Denver), another Democratic Socialist, by a narrow 41–34 percent margin.
Colorado is the only state holding a June 30 primary, and the key contests are shaping up to deliver another round of closely watched and potentially consequential results.
