Former Obama administration adviser Dan Pfeiffer is warning that a string of progressive primary victories should serve as a major wake-up call for Democratic Party leaders, arguing that the party’s traditional establishment is rapidly losing its influence.
Speaking on Pod Save America, Pfeiffer and fellow former Obama official Jon Favreau discussed the recent Democratic primary elections in New York, where several progressive candidates backed by New York City Mayor Zohran Mamdani secured key victories over establishment opponents.
Among the winners were Claire Valdez, Brad Lander and Darializa Avila Chevalier, all of whom prevailed in their respective primaries. Each candidate received Mamdani’s endorsement.
All three candidates are progressives and critics of Israel. Two of them, Lander and Chevalier, defeated incumbent members of Congress. Lander unseated Rep. Dan Goldman, D-N.Y., while Chevalier defeated Rep. Adriano Espaillat, D-N.Y.
Pfeiffer argued that the results extend beyond New York and point to a broader political trend within the Democratic Party.
He also highlighted the campaigns of Senate candidate Graham Platner in Maine and House candidate Randy Villegas in California as additional examples of progressive candidates gaining momentum.
Villegas, a progressive college professor, was backed by Sen. Bernie Sanders, I-Vt., and Rep. Alexandria Ocasio-Cortez, D-N.Y. Sanders also endorsed Platner, a military veteran whose campaign has drawn attention because of past controversial social media posts and other issues.
According to Pfeiffer, one of the clearest lessons from the recent elections is that endorsements from longtime Democratic leaders may no longer provide the political advantage they once did.
“The thing that we should take away is, like so much else that’s happening in this country, like it’s happening when progressives beat establishment candidates in the second district of Maine, in the California race where Randy Villegas won, Graham Platner forcing Janet Mills out of the race…like, there’s a giant warning sign for the Democratic establishment here where the support of people like Schumer or even Hakeem Jeffries is certainly not an asset to your campaign, it may be a detriment,” Pfeiffer said.
Pfeiffer pointed specifically to House Minority Leader Hakeem Jeffries, D-N.Y., and Senate Minority Leader Chuck Schumer, D-N.Y., arguing that their endorsements may now carry less political value than in previous election cycles.
While he acknowledged that the overall electoral landscape remains mixed and that moderate Democratic candidates continue to receive support in some races, Pfeiffer said the recent victories by progressives—particularly those who defeated incumbents—reflect growing dissatisfaction with the party’s leadership.
He described the trend as evidence of an “antipathy” toward the Democratic establishment.
Pfeiffer also argued that several organizations aligned with the political left have gained a significant organizational advantage over the party’s traditional infrastructure.
“It is very clear that the groups of the left, Justice Democrats, Democratic Socialists of America, Our Revolution, are out-organizing, out-fundraising, out-working, out-maneuvering the traditional party institutions,” Pfeiffer said.
He continued by arguing that those organizations have captured the party’s energy by adopting more creative, strategic and aggressive approaches to campaigning.
According to Pfeiffer, Democratic leaders should view the recent election results as a serious warning about the party’s current standing and its ability to compete effectively.
“So this is a big deal,” Pfeiffer concluded, saying Democratic establishment figures should be “deeply concerned” about what the results suggest regarding the party’s organization, leadership and electoral strength moving forward.
