Leader of the Manhattan Democrats, former Assemblyman Keith Wright, said they will work on party unity and boosting voter turnout.
Meanwhile, after a contentious process that included not endorsing in the primary, the United Federation of Teachers has posted that it is endorsing Mamdani for mayor in the general election.
In a statement, UFT President Michael Mulgrew said the city needs a mayor "who understands the task before us and who will help us get it done," referencing the need to protect public education, public employees and public service from attacks from Washington, D.C., and make the city safer and more affordable for families.
As for the other candidates in the race, Mayor Eric Adams, who is running on the independent line, said Former Governor Andrew Cuomo urged him to drop his bid for reelection.
"He caved into the far left around bail reform, around all of these other entities, and now he's telling me that I should step aside for him. That's the highest level of arrogance that I've ever witnessed," Adams said.

Cuomo's campaign issued a statement saying, "Mayor Adams did not run in the Democratic primary because he knew he was anathema to Democrats and unelectable. Nothing has changed. We do not see any path to victory for Mayor Adams."
Meanwhile, Jim Walden, an attorney who is running for mayor as an independent, is "The Man with The Plan," or so he thinks.
"If you've got candidates that are splitting the vote, all you're going to do is allow the socialists to walk into City Hall," Walden said.
Mamdani shocked the city's political establishment by winning the Democratic primary.
Walden says he and the remaining candidates: Cuomo, Mayor Adams and radio host Curtis Sliwa should get behind a single candidate to face Mamdani in the fall. The challenger would be determined by a public opinion poll in October.
"That is a robust poll, one of the largest polls we've seen by an independent agency. Winner take all," Walden said.
Former Governor David Patterson and other centrists support it. Cuomo says he's considering it, but not Sliwa, and not the mayor.
"It's not a good idea," Adams said when asked if he would endorse the idea.
The proof, he says, is that the primary polls predicted that Cuomo would win.
"We just saw a campaign that a person was up 32 points and lost by 12 points. So, why are we going to believe another concept like that again?" Adams said.
When asked what it would take for Adams to drop out, the mayor said, "When I win. I don't have to. There's no reason to drop out."
Pollster Lee Miringoff predicted Cuomo would win the primary. He says any poll is just a snapshot in time.
"I don't like polling to tell candidates whether they should run or not," said Miringoff, director of Marist Poll. "It doesn't provide a lot of metrics about fundraising, endorsements, turnout on the actual Election Day and what might happen from the time of the poll until the actual time voters would be voting."
