Last week, several outlets reported that the Trump administration has been working behind the scenes to clear the field for Cuomo by offering administration posts to other mayoral candidates, including Democratic Mayor Eric Adams, and Republican contender Curtis Sliwa in exchange for them dropping out of the race.
Cuomo's identity as Trump's horse has ratcheted up the pressure for top Democratic leaders—namely the Empire state duo of House Minority Leader Hakeem Jeffries and Senate Minority Leader Chuck Schumer—to throw their weight behind Mamdani. But with the election now less than two months away, they have still refused to budge, to the increasing frustration of the party's base and its progressive leaders.
Last week, Rep. Alexandria Ocasio-Cortez (D-N.Y.) called out these leaders directly, asking on the steps of the Capitol: "Are we a party who rallies behind our nominee or not?"
"I am very concerned about the example that is being set by anybody in our party," she continued. "If an individual doesn't want to support the party's nominee now, it complicates their ability to ask voters to support any nominee later."
During a stop on his "Fighting Oligarchy" tour, Sen. Bernie Sanders (I-Vt.), a Brooklyn native, said New York Democrats should be "jumping up and down" to support a candidate who has galvanized young voters like Mamdani.
Speaking of party leadership, Sanders said: "It's no great secret that they're way out of touch with grassroots America, with the working families of this country, not only in New York City, but all over this country."
That sentiment was shared by the liberal tastemakers on the popular podcast Pod Save America. Former Obama speechwriter Jon Favreau called out leadership by name, saying their hesitancy to endorse Mamdani was "pathetic."
"Donald Trump's going to try to get Eric Adams out of the race so he can help Andrew Cuomo," Favreau said. "Meanwhile, Hakeem Jeffries and Chuck Schumer have not yet endorsed the candidate who won the Democratic primary in New York City, the choice of the Democratic voters. Because why, because they don't want to get involved in a primary in a city, in the state they represent?"
Favreau questioned what happened to the "rule that when a Democrat wins the primary, we've all got to unite behind the nominee... because we are facing an authoritarian threat."
Cuomo, he said, "is basically participating" in that threat by being "on Donald Trump's side."
According to CNN, this reluctance is widespread across New York Democrats:
Reps. Yvette Clarke, Dan Goldman and Ritchie Torres have not said they plan to support Mamdani. Rep. Gregory Meeks, who endorsed Cuomo in the primary, has also remained silent along with Rep. Grace Meng, who represents parts of Queens.
New York Gov. Kathy Hochul and Mamdani have had "a number of conversations," Hochul said recently, and the two have met in person. Speaking separately to a Politico reporter, Hochul dismissed the talks between Adams and Trump aides with a profanity. Still, she has not made an endorsement.
Sources told CNN that the reticence stems in some part from the "public threat by Mamdani's democratic socialist allies to primary Jeffries and other congressmen" as well as Mamdani's "ties to democratic socialists and his criticism of Israel."
Sanders countered that Mamdani's were "not radical ideas."
"We're the richest country in the history of the world," he said. "There's no excuse for people not having affordable housing, good quality, affordable, decent transportation, free transportation."
Not only did the Times/Siena poll find Mamdani leading in the coming election, but voters also said they trusted him most on issues across the board, including ones that party grandees fear will be liabilities.
He holds leads over all comers, not only on his bread and butter issues of affordability and housing, but also on crime, taxation, and the Israeli-Palestinian conflict.
In an interview on CNN, former Obama campaign manager David Axelrod suggested that the refusal to back Mamdani was probably the result of "donor pressure."
Though Mamdani has surged in recent months with small-dollar donors, big money in the city has been behind Cuomo and other centrist candidates.
The biggest of these is the billionaire-funded Fix the City PAC, which received an $8.3 million donation from former New York Mayor Michael Bloomberg, and as of late August had dropped more than $15 million to keep Cuomo afloat.
Another fund, called New Yorkers for a Better Future Mayor '25 has yet to declare a favorite, but has both barrels locked on Mamdani. Under a similar name, this PAC marshalled support for more than a dozen corporate-friendly city council candidates early this year, with support from the pro-Israel hedge fund manager Bill Ackman and several major players in New York's real estate industry. It has announced a goal of raising $25 million to defeat Mamdani in November.
Axelrod said that the party leadership's fealty to these donors over the groundswell of support for Mamdani was "a mistake."
"He ran on the issue of affordability and on a kind of positive politics that got—as Bernie said—many, many young people in that city to involve themselves in the process," he said.
Axelrod also added that, despite Jeffries' claim that Mamdani has yet to win over voters in the House leader's district, the insurgent candidate, in fact, "carried Hakeem Jeffries' district" by a 12-point margin.
Former Sanders foreign policy adviser Matt Duss said that Axelrod's diagnosis of "donor pressure" was "correct."
"But," he said, "we should also be completely clear that 'donor pressure' is just a polite way of saying 'political corruption.'"
