Only 48 hours prior to the New York race for mayor, Michael Lange made a bold electoral prediction – going beyond the winner citywide, but precinct by precinct. The analyst, a political analyst born and raised in New York City, devoted over a decade in left-leaning activism and emerged as a kind of local celebrity this year for his deep dives into municipal statistics and polling.

He released his highly detailed forecast map – which correctly forecast that the progressive candidate would win while failed to predict the independent candidate’s solid showing – on his newsletter, his platform. He possesses a talent for witty coinages. He highlighted, as an example, the split between the progressive stronghold, stretching from Park Slope to another area to a third locale, where he forecasted (accurately) that Mamdani would win by large leads, and the “capitalist corridor” on affluent parts of Manhattan. There, “the Free Press and financial newspapers surpass the New York Times” in readership and most voters favored the independent, campaigning as a moderate alternative.

Election Night Trends and Surprises

What was your election night?

I had to do that because they were adding approximately 200K ballots into the tally frequently! I was actually somewhat anxious initially: The candidate led the initial ballots by 12 points, but there were two big batches of ballots added later and the advantage dropped from 12% to 8%. It was concerning.

Understand, it was possible where yesterday went kind of poorly for Mamdani, where the opponent was going to end up essentially doubling his votes from the earlier contest. But the winner added 500,000 votes to his initial base, and this was critical why he succeeded. He went out and massively expanded his support from the first round.

Coalition Building

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

He assembled the coalition that the left long aimed for: diverse racially, youthful, tenants and it’s people squeezed by affordability. He gained significantly with Black and Hispanic voters, working- and middle-class voters, compared to the primary. Plus he boosted his core of liberal progressives, young leftists, and immigrant groups. Victory required without expanding his appeal.

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

It’s definitely a genuine phenomenon, confined to Hispanic laborers, south Asians and Muslims. Voters in immigrant strongholds that went for Trump previously backed Zohran this year. But it’s not that he was winning over white working-class voters and Trump loyalists.

Turnout and Impact

A major development of the night was the record participation. Who did that help?

Both sides. Participation was significantly higher than anticipated. I thought we might go over two million, but it’s closer to 2.3 million – that is a huge number of participants. There was a substantial anti-Mamdani block, energized, but the Mamdani base was also motivated, and that was enough to win.

You forecasted he’d get over half the ballots. Is he on course for that?

Right now it appears he’s likely to surpass half. He has just over 50% but remain around 200K ballots uncounted at that time. So it’s not certain, but I believe probable, and I wish he does so afterwards no one can say Sliwa was a disruptor.

Republican Collapse

Curtis Sliwa, 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 area. That really surprised me. Cuomo kept Caucasian districts, very wealthy areas and devout communities, and plus gained all of these Republicans on the island with a high participation. I think there was a lot of tactical voting by GOP voters. They were doing it before Trump tweeted his support for Cuomo, but that definitely helped. It could have even turned the tide if the winning alliance failed to expand.

Progressive Strongholds

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

In my view there was a little dilution of the progressive zone in some areas like neighborhoods that have more older white ethnic folks. In Astoria, instance, the property owners and residents all went for the independent. So there existed some opposition. However no, largely the commie corridor is another huge reason why Mamdani won – he was polling between 77% and 83% in specific neighborhoods.

Community Support

In the lead-up to the election we reported on whether the candidate was gaining ground with Jewish New Yorkers. Is there any suggestion that he did?

Exist areas with many secular and more progressive-leaning Jews – such as specific locales – where he performed strongly. But in the wealthy Jewish communities like the Manhattan area, his position on Israel definitely mattered there. Similarly in the more middle-class Jewish areas including Queens neighborhoods, or Bronx areas – they favored Cuomo. And also, you have newcomers from Eastern Europe in the borough, who were strongly Cuomo. Therefore I don’t know if existed crazy narrative-busters here, but he did hold left-leaning areas and including sections of the Upper West Side by big margins.

Long-Term Significance

Did Mamdani redefine what the city means politically? Will commie corridor become a launch pad for leftwing candidates?

Yes, it’s not accidental that some of the biggest political leaders from progressives hail from a handful of neighborhoods in the boroughs. I’m sure that we’ll see more of that – candidates will come from these areas to be elevated nationally.

However I believe that each urban center in the US could develop their own commie corridor. Cities are the epicenters of leftwing power in the nation – since they’re young, people rent and they are places where people are crushed by the disparities we face.
