The dust has finally settled on one of the most chaotic chapters in New York City political history. If you spent any time watching the news in early 2025, you know the vibe was basically a mix of a high-stakes legal thriller and a very expensive reality show. But now that we’re in 2026 and the new administration is actually moving into Gracie Mansion, it's worth looking back at the NYC mayor democratic primary because, honestly, what actually happened was way weirder than the headlines suggested.
Most people think it was just a simple story of an incumbent falling from grace. It wasn't. It was a perfect storm of federal indictments, the return of a political "ghost," and a massive shift in how New Yorkers actually use ranked-choice voting.
The Shocking Collapse of the Adams Campaign
Let’s be real: Eric Adams starting 2025 as the incumbent should have made him the favorite. But the federal corruption case changed everything. While Judge Dale Ho eventually dismissed the charges with prejudice in April 2025—citing that the DOJ shouldn't be forced to prosecute if they didn't want to—the political damage was already a total wreck.
Adams did something nobody saw coming. On April 3, 2025, he withdrew from the Democratic primary entirely. He didn't quit the race, though. He decided to run as an independent, thinking he could bypass the progressive base of the Democratic party and appeal directly to the "silent majority" in the general. It was a massive gamble.
It failed.

By September, with his poll numbers tanking and his fundraising drying up, he dropped out of the general election too. He left the city with a bizarre "My Way" exit video and no successor. This vacuum turned the NYC mayor democratic primary into a wide-open brawl that most of the "smart" money in the city completely misjudged.
The Return of the King (or Not)
When Andrew Cuomo entered the race in March 2025, the political establishment had a collective heart attack. He campaigned on a "Fight and Deliver" platform, leaning hard into his experience as governor. For a few months, it actually looked like he might pull it off. He had the money. He had the name recognition. He even had a late-game endorsement from Michael Bloomberg.
But Cuomo ran into a wall he didn't expect: the "Anyone But Cuomo" coalition.
In the June 24 primary, the math was brutal. While Cuomo led in early polls, the ranked-choice voting (RCV) system became his undoing. People forget that in RCV, you don't just need to be someone's first choice; you need to not be their last choice.

The progressive wing of the party, usually known for infighting, actually got their act together. Groups like the Working Families Party and the "DREAM" campaign told voters to rank anyone—Brad Lander, Zellnor Myrie, Adrienne Adams—as long as they didn't rank Cuomo.
The Final Primary Standings (June 24, 2025)
The numbers tell a story of a city deeply divided by generation and geography:
- Zohran Mamdani: 56.4% (Final Round)
- Andrew Cuomo: 43.6% (Final Round)
- Brad Lander: Eliminated in Round 3
- Adrienne Adams: Eliminated in Round 2
Mamdani’s win wasn't just a narrow victory; it was a 12-point blowout in the final tabulation. He absolutely dominated in Brooklyn and Western Queens, while Cuomo held onto the Bronx and Staten Island.
Why Zohran Mamdani Actually Won
If you had asked a pundit in 2024 if a 33-year-old Democratic Socialist Assemblyman could win the NYC mayor democratic primary, they would have laughed you out of the room. So, how did it happen?

- The "Free Bus" Effect: Mamdani didn't talk in vague policy terms. He promised free city buses and a rent freeze. Whether or not these are actually "doable" is still a massive debate in the City Council right now, but as a campaign slogan? It was gold.
- The AOC Factor: Alexandria Ocasio-Cortez didn't just endorse him; she lived on the trail for him. Her ability to mobilize young voters who usually skip primaries was the "secret sauce."
- The Ground Game: While Cuomo was buying TV ads, Mamdani had tens of thousands of volunteers knocking on doors. It sounds cliché, but in a low-turnout primary, that's how you win.
Honestly, the most surprising thing was the "cross-endorsement" strategy. Mamdani and Brad Lander endorsed each other as second choices. It was a "good cop, bad cop" routine that kept the progressive vote from splitting. About 61% of Lander’s voters put Mamdani as their second choice. That’s what killed Cuomo’s chances.
The 2026 Reality Check
Now that we’re in 2026, the "vibes" of the primary are meeting the "math" of the city budget. Mayor Mamdani is finding out that freezing rent is a lot harder than tweeting about it. He’s already facing a massive standoff with the real estate industry and some pushback from Governor Kathy Hochul, who is keeping a very close eye on the city's tax revenue.
The primary taught us that the old-school "machine" politics in NYC is effectively dead. You can't just rely on name recognition and a big bank account anymore. You need a movement.
What You Should Do Now
If you're trying to keep up with how the fallout of the NYC mayor democratic primary is affecting your daily life in the city, here’s the move:
- Watch the City Council hearings on the "Department of Community Safety": This was Mamdani's big campaign promise to replace some NYPD functions with mental health workers. It’s the biggest budget fight of 2026.
- Check your rent stabilization status: The Mayor is pushing for a total freeze through the Rent Guidelines Board. If you’re in a rent-stabilized unit, this is the year to pay attention to those board meetings in June.
- Follow the "Free Bus" pilot: The M14 and B46 are the first targets for the fare-free expansion. If you commute on those lines, your wallet is about to feel the impact of that June primary victory.
The 2025 election wasn't just a change in leadership; it was a total rewrite of the NYC political playbook. Whether you love the new direction or you're already missing the "moderate" days, there's no denying that the city is in a completely different era now.
