What the Evidence Shows
The claim that "hundreds of police officers are threatening to quit if Communist Zohran Mamdani is elected NYC Mayor" combines two assertions: a mass police resignation threat and Mamdani's identification as a communist.
None of the provided sources mention any police officers threatening to quit over Mamdani's candidacy or potential election. The sources focus on his political platform, polling status, and public perception but do not report any organized police opposition or resignation threats.
Multiple reputable sources clarify Mamdani's political stance. PolitiFact explicitly states that claims labeling Mamdani as a communist are false, noting that while he is a democratic socialist advocating for affordability reforms, he does not support government takeover of industry or other core communist tenets.politifact.compolitifact.comPolitiFact
BBC News reports that former President Trump called Mamdani a "pure communist" and threatened to cut federal funding if he wins, but this is presented as a political attack rather than an objective fact. The source does not confirm the truth of the communist label.bbc.combbc.comZohran Mamdani: 'I don't think we should have billionaires,' says NYC mayoral...
Polling data and campaign analyses focus on Mamdani's lead in the mayoral race and his support base but do not mention police opposition or mass resignation threats.fox5ny.comfox5ny.comZohran Mamdani: Can the 33-year-old democratic socialist become NYC's next...

The absence of any mention of police quitting threats in these multiple independent and reliable news sources suggests that this claim lacks evidentiary support and is likely misinformation or exaggeration.
In summary, the claim conflates an unsubstantiated threat from police officers with a mischaracterization of Mamdani's political ideology. The evidence strongly indicates that labeling him as a communist is false and that no credible reports exist about mass police quitting threats tied to his candidacy.
