Just 48 hours prior to the NYC mayoral election, Michael Lange made a bold forecast – not just who would win overall, but precinct by precinct. Lange, an expert in elections who grew up in New York City, has spent more than ten years in progressive politics and has become something of a local celebrity this year for his thorough analyses into city data and polling.

He released his highly detailed prediction map – which correctly forecast that the progressive candidate would win while missing the independent candidate’s strong performance – on his Substack, his platform. Lange has a flair for clever terms. He pointed out, as an example, the split between the “commie corridor”, stretching from Park Slope to another area to Astoria, where he predicted (correctly) that the left-wing candidate would win by large leads, and the conservative-leaning zone on affluent parts of Manhattan. In those areas, certain media outlets and Wall Street Journal surpass the mainstream paper” in readership and most voters favored Cuomo, who ran as a conservative-courting independent.

Voting Day Patterns and Unexpected Results

How was your election night?

I had to do that since they were dropping around 200,000 ballots into the tally frequently! I was actually a little nervous initially: Mamdani was ahead the initial ballots by a dozen percentage points, but came two big batches of ballots that came in after that and the advantage dropped from 12% to 8%. It was concerning.

Understand, it was possible in which election day turned out somewhat badly for him, in which Cuomo would have basically increasing his support from the Democratic primary. However Mamdani gained 500,000 votes to his primary coalition, and that’s a huge reason why he succeeded. He campaigned and massively expanded his base from the first round.

Coalition Building

Where did Mamdani gain additional support from?

He built the coalition that the left always wanted to build: it’s multiracial, youthful, tenants and individuals facing cost pressures. He improved considerably with minority communities, everyday New Yorkers, compared to the primary. Plus he boosted his core of liberal progressives, youthful radicals, and immigrant groups. Victory required without expanding his appeal.

He built the alliance that progressives long aimed for: multiracial, youthful, renters and people struggling with costs

There were also a number of supporters of both candidates – is that a big trend?

It is a genuine phenomenon, limited to Hispanic laborers, Asian communities and Muslims. Electors in ethnic enclaves that supported Trump previously went for Zohran this year. However it’s not that he was winning over white working-class voters and Trump loyalists.

Voter Participation and Effects

A major development of the night was the sky-high participation. Who did that help?

Each candidate. Turnout was significantly higher than I had expected. I figured it could go over two million, but it reached 2.3 million – which is a huge number of participants. Existed a substantial anti-Mamdani block, energized, but the Mamdani base was also motivated, and that sufficed to win.

You forecasted he’d exceed half the ballots. Is he likely for that?

Right now it appears he’s favored to get over 50%. He has just over 50% but there’s still probably 200,000 votes uncounted at that time. So I don’t think certain, but I believe it’s likely, and I hope he does because afterwards none can claim Sliwa was a spoiler.

GOP Decline

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

He lost any district in any borough. Including one neighborhood in the borough, which is like an 88% Trump neighborhood. That really surprised me. The independent kept very white areas, affluent zones and devout communities, and then added all of these Republicans on the island with a high participation. I believe occurred a lot of tactical voting by GOP voters. This happened prior to the former president tweeted his support for the candidate, but that definitely helped. It might have changed the outcome if the winning alliance hadn’t grown.

The “Commie Corridor”

Regarding your much mentioned left-wing base – was support for the candidate dominant in those parts of the boroughs?

In my view there was some weakening of the commie corridor in certain places like Astoria or Greenpoint that have more older white ethnic folks. In Astoria, for example, the Greek landlords and residents supported Cuomo. Thus there was a little resistance. However no, mostly the commie corridor is another huge reason why Mamdani prevailed – he was polling between high percentages in Fort Greene, Clinton Hill and Bushwick.

Community Support

In the lead-up to the election we reported on if Mamdani was making inroads with Jewish New Yorkers. Is there any suggestion that he did?

There are areas with a lot of non-religious and left-inclined voters – such as Park Slope and Morningside Heights – where he did well. But in the wealthy Jewish communities like the Manhattan area, his Middle East stance was influential in those places. Likewise in the moderate communities like Forest Hills, Rego Park, or Spuyten Duyvil and Riverdale – they favored the independent. Plus, there are newcomers from Eastern Europe in southern Brooklyn, who were pretty staunchly supportive. Therefore it’s unclear if existed major surprises on this one, but Mamdani did hold more progressive Jewish neighborhoods and including sections of the another locale by big margins.

Long-Term Significance

Did Mamdani redefine what New York means politically? Will the commie corridor serve as a springboard for leftwing candidates?

Yes, it’s no coincidence that some of the biggest political leaders from progressives hail from a handful of neighborhoods in Brooklyn, Queens and the Bronx. I believe that we’ll see more of that – candidates will emerge from these areas to be promoted to higher office.

However I think that every city in America can have similar progressive hubs. Urban places are the centers of progressive influence in the nation – since they’re young, tenancy is common and they represent locales where individuals struggle by the inequalities we face.
