Only 48 hours before the NYC mayoral election, Michael Lange made a bold forecast – going beyond the winner citywide, but precinct by precinct. Lange, a political analyst who grew up in New York City, devoted more than ten years in progressive politics and has become something of a well-known figure this year for his deep dives into city data and polling.

He published his extremely precise forecast map – which correctly forecast that Zohran Mamdani would win although missing the independent candidate’s strong performance – on his newsletter, his platform. Lange possesses a talent for witty coinages. He pointed out, as an example, the divide between the progressive stronghold, stretching from one neighborhood to another area to Astoria, where he predicted (correctly) that Mamdani would triumph by large leads, and the “capitalist corridor” on affluent parts of Manhattan. In those areas, “the Free Press and financial newspapers surpass the mainstream paper” in audience and the majority of electors favored the independent, who ran as a moderate alternative.

Election Night Patterns and Surprises

What was your election night?

It was necessary because they were adding around 200,000 votes into the tally every few minutes! I felt somewhat anxious at the beginning: Mamdani led the initial ballots by a dozen percentage points, but there were two big batches of votes that came in later and the advantage went from 12 to 8%. It was concerning.

Understand, it was possible where yesterday went somewhat badly for him, in which Cuomo would have basically increasing his support from the Democratic primary. However the winner added half a million votes to his primary coalition, and that’s a huge reason why he won. He went out and greatly broadened his base from the primary.

Coalition Building

How did the mayor-elect get those extra votes from?

He built the alliance that progressives always wanted to build: it’s multiracial, it’s young, tenants and it’s people facing cost pressures. He improved significantly with Black and Hispanic voters, everyday New Yorkers, compared to the primary. Plus he boosted his core of left-leaning activists, young leftists, and immigrant groups. He couldn’t have won without making those significant inroads.

Additionally, there were a number of Trump/Mamdani voters – is this significant?

It’s definitely a real thing, confined to working-class Latinos, south Asians and Muslims. Voters in ethnic enclaves that supported Trump previously went for Zohran this year. But I wouldn’t say he was winning over Caucasian laborers and Maga voters.

Turnout and Impact

One of the big stories of the night was the record participation. Who did that help?

Both sides. Participation was significantly higher than I had expected. I figured we might go over 2 million, but it’s closer to 2.3M – that is a lot of darn voters. There was a substantial opposition group, energized, but his supporters was equally driven, and that was enough to secure victory.

You predicted he’d exceed 50% of the vote. Is he likely for that?

Currently you would say he’s likely to get over half. He’s at 50.4% but there’s still around 200K ballots uncounted at that time. So it’s not certain, but I think probable, and I hope he does so afterwards none can claim Sliwa was a disruptor.

GOP Decline

The GOP candidate, the conservative contender, is the other big story. His vote plummeted.

He lost any district in any borough. Not even one neighborhood in Staten Island, which is like an highly conservative area. That truly surprised me. Cuomo held Caucasian districts, affluent zones and devout communities, and then added all of these Republicans on Staten Island who had a high participation. I believe there was significant tactical voting by the Republicans. This happened before the former president endorsed for the candidate, but that definitely helped. It might have changed the outcome unless Mamdani’s coalition hadn’t grown.

Progressive Strongholds

What about your much mentioned “commie corridor” – did backing for Mamdani dominant in those areas of Brooklyn and Queens?

In my view existed a little dilution of the progressive zone in some areas like Astoria or Greenpoint that have more older white ethnic folks. In Astoria, instance, the property owners and homeowners supported Cuomo. So there was a little resistance. But overall, largely the leftist base is another huge reason why Mamdani prevailed – he scored between 77% and 83% in Fort Greene, Clinton Hill and Bushwick.

Jewish Voters

In the lead-up to the vote there was coverage on if Mamdani was making inroads with the community. Is there any suggestion that he succeeded?

There are neighborhoods with a lot of secular and more progressive-leaning Jews – like specific locales – where he did well. But in the wealthy Jewish communities like the Manhattan area, his Middle East stance definitely mattered there. Likewise in the more middle-class Jewish areas including Forest Hills, Rego Park, or Spuyten Duyvil and Riverdale – they all leaned Cuomo. Plus, you have newcomers from the former Soviet Union in southern Brooklyn, who were pretty staunchly Cuomo. Therefore I don’t know if existed major surprises on this one, but Mamdani did hold left-leaning areas and including sections of the Upper West Side with large leads.

Long-Term Significance

Did Mamdani redefine what New York means politically? Will the progressive base become a launch pad for progressive contenders?

Absolutely, it’s not accidental that some of the biggest figures from progressives come from a handful of neighborhoods in the boroughs. I’m sure that we’ll see additional examples – people will come from these areas to be elevated nationally.

But I believe that every city in the US can have their own commie corridor. Urban places are the epicenters of leftwing power in America – since youth reside there, tenancy is common and they represent locales where individuals struggle by the disparities exist.
