Only two days before the New York race for mayor, Michael Lange issued a significant forecast – going beyond the winner citywide, but block by block. The analyst, an expert in elections born and raised in the city, has spent over a decade in progressive politics and has become something of a local celebrity this year for his deep dives into municipal statistics and voter surveys.

He published his highly detailed prediction map – which correctly forecast that Zohran Mamdani was victorious while failed to predict Andrew Cuomo’s strong performance – on his newsletter, his platform. Lange has a flair for clever terms. He highlighted, as an example, the divide between the “commie corridor”, running from one neighborhood to Bushwick to a third locale, where he predicted (correctly) that Mamdani would triumph by large leads, and the “capitalist corridor” on Manhattan’s Upper East and Upper West Sides. In those areas, certain media outlets and Wall Street Journal surpass the New York Times” in audience and the majority of electors leaned toward Cuomo, who ran as a moderate alternative.

Voting Day Trends and Unexpected Results

How was your night?

I had to do that since they were dropping around 200,000 votes into the tally frequently! I felt a little nervous at the beginning: Mamdani was ahead the early vote by 12 points, but there were two big batches of ballots that came in later and his lead dropped from 12 to 8%. It was concerning.

You know, there was a world where election day turned out kind of poorly for Mamdani, in which Cuomo would have essentially increasing his support from the earlier contest. However the winner gained half a million supporters to his initial base, and that’s a huge reason why he won. He campaigned and greatly broadened his support from the primary.

Coalition Building

Where did the mayor-elect gain additional support from?

He built the alliance that progressives always wanted to build: diverse racially, it’s young, it’s renters and it’s people squeezed by affordability. He gained considerably with minority communities, working- and middle-class voters, relative to the primary. Plus he boosted his base of liberal progressives, young leftists, and immigrant groups. He couldn’t have won without making those significant inroads.

There were also a number of Trump/Mamdani voters – is that a big trend?

It is a genuine phenomenon, confined to Hispanic laborers, south Asians and Islamic voters. Electors in immigrant strongholds that supported Trump previously backed Zohran this year. But it’s not that he was gaining white working-class voters and Trump loyalists.

Voter Participation and Effects

One of the big stories of the election was the record turnout. Who did that help?

Each candidate. Participation was significantly higher than I had expected. I figured we might exceed two million, but it reached 2.3 million – that is a huge number of participants. There was a substantial anti-Mamdani block, energized, but his supporters was equally driven, and that was enough 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 surpass 50%. He has just over 50% but there’s still probably 200K ballots left to report at that time. So it’s not certain, but I think probable, and I wish he does because afterwards no one can say Sliwa was a disruptor.

Republican Collapse

The GOP candidate, the Republican candidate, was another surprise. His support completely collapsed.

He lost a single precinct in any area. Including Tottenville in the borough, which is like an 88% Trump neighborhood. That truly surprised me. Cuomo kept Caucasian districts, affluent zones and very religiously Jewish areas, and then added many conservatives on Staten Island with a strong turnout. I believe occurred a lot of strategic balloting by the Republicans. They were doing it prior to the former president endorsed for the candidate, but that definitely helped. It could have even turned the tide if the winning alliance failed to expand.

The “Commie Corridor”

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

I think existed a little dilution of the progressive zone in certain places like neighborhoods that have more older white ethnic folks. There, instance, the property owners and residents all went for the independent. So there existed a little resistance. However no, mostly the commie corridor is another huge reason why Zohran won – he scored between 77% and 83% in specific neighborhoods.

Community Support

Prior to the vote there was coverage on if Mamdani was making inroads with the community. Any indication that he did?

There are neighborhoods with a lot of secular and more progressive-leaning Jews – such as specific locales – where he did well. However in the affluent districts such as the Upper East Side, his Middle East stance was influential in those places. Similarly in the moderate communities like Forest Hills, Rego Park, or Spuyten Duyvil and Riverdale – they favored the independent. Plus, there are Jewish immigrants from Eastern Europe in the borough, they were pretty staunchly Cuomo. So I don’t know if existed major surprises on this one, but Mamdani did hold left-leaning areas and even parts of the another locale with large leads.

Political Impact

Did Mamdani redefine what New York represents in politics? Will the commie corridor become a launch pad for progressive contenders?

Absolutely, it’s no coincidence that some of the biggest figures from the left hail from a few areas in the boroughs. I believe that we’ll see more of that – candidates will come from these neighborhoods to be promoted to higher office.

But I believe that each urban center in America can have similar progressive hubs. Cities are the epicenters of progressive influence in the nation – since they’re young, people rent and they represent locales where individuals struggle by the disparities we face.
