Only two days prior to the New York race for mayor, Michael Lange made a significant forecast – going beyond who would win overall, and block by block. Lange, a political analyst who grew up in the city, has spent more than ten years in left-leaning activism and emerged as something of a well-known figure this year for his deep dives into city data and polling.

He published his extremely precise forecast map – accurately predicting that Zohran Mamdani would win although failed to predict Andrew Cuomo’s solid showing – on his newsletter, his platform. He has a flair for witty coinages. He highlighted, as an example, the split between the “commie corridor”, running from Park Slope to Bushwick to Astoria, where he predicted (correctly) that Mamdani would triumph by huge margins, and the conservative-leaning zone on affluent parts of Manhattan. In those areas, certain media outlets and Wall Street Journal surpass the New York Times” in readership and most voters leaned toward the independent, campaigning as a conservative-courting independent.

Election Night Trends and Surprises

How was your night?

It was necessary since they were adding around 200,000 ballots into the system every few minutes! I was actually somewhat anxious at the beginning: The candidate was ahead the initial ballots by 12 points, but came two big batches of ballots added later and the advantage dropped from 12 to 8%. It was concerning.

Understand, there was a world where election day turned out kind of poorly for Mamdani, in which the opponent was going to end up basically increasing his support from the earlier contest. However Mamdani added 500,000 votes to his initial base, and this was critical why he succeeded. He campaigned and massively expanded his support from the first round.

Expanding Support

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

He built the alliance that progressives long aimed for: diverse racially, youthful, tenants and individuals squeezed by affordability. He gained significantly with Black and Hispanic voters, everyday New Yorkers, compared to the primary. Additionally he further maximized his base of left-leaning activists, youthful radicals, and immigrant groups. Victory required without expanding his appeal.

He built the coalition that the left long aimed for: multiracial, young, renters and residents squeezed by affordability

Additionally, there were a number of Trump/Mamdani voters – is that a big trend?

It is a real thing, limited to Hispanic laborers, south Asians and Muslims. Electors in ethnic enclaves that went for Trump previously went for the progressive now. But it’s not that he was winning over Caucasian laborers and Maga voters.

Voter Participation and Impact

A major development of the election was the sky-high turnout. Who did that help?

Each candidate. Turnout was significantly higher than anticipated. I figured we might exceed two million, but it’s closer to 2.3 million – that is a huge number of participants. Existed a decent anti-Mamdani block, who were motivated, but his supporters was equally driven, and that was enough to win.

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

Right now it appears he’s favored to surpass half. He’s at 50.4% but there’s still probably 200K ballots left to report as of Wednesday morning. So I don’t think it’s definitive, but I believe probable, and I wish he achieves it because then no one can say Sliwa was a disruptor.

Republican Collapse

The GOP candidate, the conservative contender, is the other big story. His support completely collapsed.

He lost any district in any borough. Including Tottenville in Staten Island, which is like an 88% Trump area. That really surprised me. Cuomo kept Caucasian districts, very wealthy areas and very religiously Jewish areas, and plus gained all of these Republicans on Staten Island who had a strong turnout. I think there was a lot of tactical voting by the Republicans. This happened prior to Trump tweeted his support for the candidate, but that definitely helped. It might have changed the outcome unless the winning alliance hadn’t grown.

Progressive Strongholds

Regarding your often-discussed left-wing base – was support for the candidate dominant in those parts of Brooklyn and Queens?

In my view existed some weakening of the commie corridor in certain places like neighborhoods that have more older white ethnic folks. In Astoria, instance, the Greek landlords and homeowners supported the independent. Thus there existed some opposition. But overall, largely the commie corridor is a key factor why Mamdani won – he scored between high percentages in Fort Greene, Clinton Hill and Bushwick.

Community Support

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

There are neighborhoods with a lot of non-religious and left-inclined voters – such as specific locales – where he performed strongly. But in the affluent districts like the Upper East Side, his position on Israel definitely mattered there. Similarly in the more middle-class Jewish areas like Queens neighborhoods, or Spuyten Duyvil and Riverdale – they favored Cuomo. Plus, there are Jewish immigrants from Eastern Europe in the borough, who were strongly supportive. So I don’t know if there were major surprises on this one, but Mamdani did hold left-leaning areas and even parts of the another locale by big margins.

Long-Term Significance

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

Absolutely, it’s not accidental that key political leaders from the left hail from a handful of neighborhoods in Brooklyn, Queens and the Bronx. I believe that we’ll see more of that – people will emerge from these areas to be elevated nationally.

However I think that each urban center in the US can have similar progressive hubs. Cities are the epicenters of leftwing power in America – since youth reside there, people rent and they represent locales where individuals struggle by the inequalities exist.
