On June 24th, Zohran Mamdani delivered a political shockwave: he clinched the Democratic nomination for Mayor of New York City, defeating former Governor Andrew Cuomo. While factors like grassroots organizing and an unwavering dedication to consistent, kitchen-table focused messaging had a big impact on Mamdani’s popularity, one other element stood out: leaning into social media buzz to supercharge his campaign.
🚀 Viral Momentum & Youth-Driven Reach
Mamdani’s online rise was fueled by candid, viral-ready posts and influencer amplification. Platforms like X and TikTok became perfect stages for his speeches and priorities, reaching younger voters, whose concerns aren’t often acknowledged.
His campaign became a social media phenomenon, skillfully harnessing viral content to energize young and progressive voters.
- Breaking beyond conventional ads: Mamdani flooded feeds with authentic, eye-catching videos—from policy explainers in Hindi using mango lassi as a prop (viewed over 5 million times on X), to plunging into icy Coney Island waters to promote rent-freezing policies.
- Massive follower growth: By early June, he had amassed well over 1 million followers across TikTok, Instagram, and X.
- Live‑media synergy: He leveraged influencer partnerships and new‑media appearances—like a short video with comedian Stavros Halkias that earned 50,000 likes in under a day.
This wasn’t just flashy content — it was sustained momentum. Mamdani seamlessly blended silliness, cultural relevance, and heartfelt storytelling to build a booming digital brand that resonated deeply The buzz surrounding his campaign translated into real-world action, invigorating grassroots volunteers and driving turnout among Gen Z–Millennial voters.
💸 Cuomo’s $30 Million Ad Blitz: Less Bang, More Backfire
Cuomo responded to Mamdani’s surging popularity by spending over $30 million in super PAC-funded attack ads, yet they weren’t able to make much of an impact. Yet, there was little to show for their money. Why? Because Mamdani’s social media strategy reframed the narrative: instead of just rebutting attacks, he owned the conversation by flooding feeds with grassroots funding wins, dynamic and energetic events, and viral endorsements.
Mamdani’s team responded to negativity with humor, authenticity, and values-based messaging. The result: Cuomo’s expensive ads looked stale next to memes, live-streamed meetups, and hashtag campaigns.
