CNN's Omar Jimenez asked Phillips about the "big tent" philosophy often promoted by Democratic leaders who believe the party should welcome lawmakers and candidates who don't agree with every aspect of its platform—politicians like anti-choice Rep. Henry Cuellar (D-Texas) and former Sen. Joe Manchin (D-W.Va.), who made millions of dollars from his coal business.
Jimenez asked whether Mamdani, a democratic socialist who stunned former Gov. Andrew Cuomo and the party's leadership in the Democratic mayoral primary last month, should also be welcomed into the party's "big tent."
"The answer ultimately is no," said Phillips, who was one of the wealthiest members of Congress before he left office to run for president in a long-shot bid against former President Joe Biden in the 2024 race—losing his home state of Minnesota and garnering just 1.7% of the vote in South Carolina, falling behind author Marianne Williamson.
Phillips admitted that "most Americans share the same values" as Mamdani, who has advocated for fare-free public transit, universal free childcare, and city-run grocery stores to operate alongside private stores and provide low-cost essentials to working families.
But he claimed that while "differences of opinion, perspective, life story, politics, and experience" are beneficial to the Democratic Party, the presence of so-called "socialists" like Mamdani is not.
"The overwhelming majority of Americans want neither far-left or far-right politics," he said without citing any supporting evidence.
Phillips appeared confident that Democratic voters across the country would recoil from candidates like Mamdani—despite recent rallies in red districts where progressive Sen. Bernie Sanders (I-Vt.) and Rep. Alexandria Ocasio-Cortez (D-N.Y.), who both endorsed Mamdani, have drawn crowds of thousands of people in recent months during Sanders' Fighting Oligarchy Tour.
In addition to Mamdani's historic success in the Democratic primary—with more New Yorkers voting for him than in any other primary election in the history of the nation's largest city—numerous polls have shown that Americans back policies like those that powered his campaign.
A poll by Child Care for Every Family in 2023 found that 92% of parents with children under age 5 supported guaranteed, government-funded childcare, including 79% of Republican parents and 83% of independent parents.
Raising taxes for corporations and wealthy households is also broadly popular, with about 6 in 10 Americans supporting the proposal in a recent Pew Research poll.
And despite efforts by centrist Democrats and Republicans to portray Mamdani's platform as radical, programs like his fare-free bus proposal have already been implemented in cities like Kansas City, Raleigh, and Boston on three of the city's busiest bus routes.
"Maybe our big tent should have less millionaire nepo heirs and more fighters for the millions of working-class people," suggested Lee on Thursday.
Matt Bruenig of the People's Policy Project also condemned Phillips for suggesting Mamdani—and ostensibly the 565,639 New Yorkers who voted for him—have no place in the party.
"The stated position here is that socialists cannot be part of the Democratic Party," said Bruenig. "Does this hold for the socialist voters too? Should they also not vote for the party? Phillips is trying to radically shrink the party. Scary stuff."
"Centrists and other moderates are spending a nontrivial amount of national political energy being mad at Zohran," he added, "which could instead be spent on [President Donald] Trump and Republicans."
As Common Dreams reported Wednesday, the progressive advocacy group Our Revolution is circulating a petition that's garnered more than 30,000 signatures from people urging Democratic leaders like House Minority Leader Hakeem Jeffries, Senate Majority Leader Chuck Schumer, and Sen. Kirsten Gillibrand—all New York Democrats who have yet to endorse their own party's mayoral candidate—not to "sabotage" Mamdani.
Despite Phillips' insistence that Mamdani doesn't belong in the party, the resistance in New York appeared to weaken a bit Thursday as Rep. Adriano Espaillat (D-N.Y.) endorsed the candidate.
"New Yorkers have spoken loud and clear," said Espaillat, who had previously backed Cuomo. "And as a lifelong Democrat, I'm endorsing the Democratic Party nominee."
