Only two days before the New York race for mayor, Michael Lange made a bold electoral prediction – not just who would win overall, and block by block. Lange, a political analyst born and raised in the city, devoted over a decade in progressive politics and has become a kind of local celebrity recently for his thorough analyses into municipal statistics and polling.

He published his extremely precise prediction map – which correctly forecast that the progressive candidate would win although missing Andrew Cuomo’s solid showing – on his Substack, the Narrative War. Lange has a flair for witty coinages. He highlighted, as an example, the split between the progressive stronghold, stretching from Park Slope to another area to Astoria, where he forecasted (accurately) that Mamdani would win by huge margins, and the “capitalist corridor” on Manhattan’s Upper East and Upper West Sides. In those areas, “the Free Press and financial newspapers outrank the New York Times” in audience and most voters favored the independent, campaigning as a conservative-courting independent.

Voting Day Patterns and Surprises

What was your night?

I had to do that since they were adding approximately 200K ballots into the tally frequently! I was actually somewhat anxious initially: Mamdani led 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.

You know, there was a world where election day turned out somewhat badly for him, where the opponent would have essentially increasing his support from the Democratic primary. But the winner added 500,000 supporters to his initial base, and that’s a huge reason why he won. He went out and massively expanded his support from the primary.

Coalition Building

How did Mamdani gain additional support from?

He assembled the alliance that progressives long aimed for: diverse racially, youthful, tenants and individuals squeezed by affordability. He gained considerably with Black and Hispanic voters, working- and middle-class voters, compared to the earlier election. Plus he further maximized his core of liberal progressives, young leftists, and immigrant groups. Victory required without expanding his appeal.

He created the alliance that progressives always wanted to build: multiracial, youthful, renters and residents struggling with costs

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

It’s definitely a genuine phenomenon, confined to working-class Latinos, south Asians and Muslims. Electors in immigrant strongholds that supported the former president last year backed the progressive this year. But it’s not that he was gaining Caucasian laborers and Trump loyalists.

Turnout and Effects

One of the big stories of the night was the sky-high participation. Who did that help?

Each candidate. Participation was significantly higher than anticipated. I figured it could exceed 2 million, but it’s closer to 2.3 million – that is a huge number of participants. There was a substantial opposition group, energized, but the Mamdani base was also motivated, and that sufficed to secure victory.

You predicted he’d get over half the ballots. Is he likely for that?

Right now it appears he’s favored to get over 50%. He has 50.4% but there’s still around 200,000 votes uncounted at that time. Thus it’s not it’s definitive, but I think it’s likely, and I hope he does because then no one can say Sliwa was a disruptor.

GOP Decline

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

He didn’t win a single precinct in any borough. Including one neighborhood in Staten Island, similar to an 88% Trump neighborhood. That truly surprised me. Cuomo kept Caucasian districts, very wealthy areas and devout communities, and plus gained all of these conservatives on the island who had a strong turnout. I think occurred significant tactical voting by GOP voters. This happened prior to Trump tweeted his support for the candidate, but that definitely helped. It could have even turned the tide if Mamdani’s coalition failed to expand.

The “Commie Corridor”

Regarding your much mentioned “commie corridor” – did backing for the candidate dominant in those parts of Brooklyn and Queens?

In my view existed a little dilution of the progressive zone in certain places like neighborhoods that have more older white ethnic folks. In Astoria, instance, the property owners and homeowners supported the independent. So there existed some opposition. But overall, largely the commie corridor is another huge reason why Mamdani prevailed – he was polling between 77% and 83% in Fort Greene, Clinton Hill and Bushwick.

Jewish Voters

Prior to the election there was coverage on whether Mamdani was making inroads with Jewish New Yorkers. Is there any suggestion that he did?

There are neighborhoods with many secular and more progressive-leaning Jews – such as specific locales – where he performed strongly. However in the affluent districts like the Manhattan area, his position on Israel was influential in those places. Similarly in the moderate communities like Forest Hills, Rego Park, or Spuyten Duyvil and Riverdale – they all leaned the independent. And also, you have newcomers from Eastern Europe in southern Brooklyn, they were strongly Cuomo. Therefore I don’t know if existed major surprises here, but Mamdani retained left-leaning areas and even parts of the Upper West Side by big margins.

Long-Term Significance

Has Mamdani rewritten what New York represents in politics? Will progressive base become a launch pad for leftwing candidates?

Yes, it’s no coincidence that key political leaders from progressives hail from a handful of neighborhoods in the boroughs. I’m sure that we’ll see additional examples – candidates will come from these neighborhoods to be elevated nationally.

But I think that every city in America can have similar progressive hubs. Urban places are the epicenters of progressive influence in the nation – because youth reside there, people rent and they are places where individuals struggle by the inequalities exist.
