Trump Supporters Backing Mamdani and a Emerging Progressive Alliance: Key Surprises from NYC’s Mayoral Race

Only two days before the NYC race for mayor, Michael Lange made a significant forecast – not just the winner citywide, and precinct by precinct. Lange, an expert in elections who grew up in the city, devoted over a decade in left-leaning activism and has become something of a local celebrity recently for his deep dives into municipal statistics and voter surveys.

He published his highly detailed prediction map – accurately predicting that Zohran Mamdani would win although missing Andrew Cuomo’s strong performance – on his newsletter, the Narrative War. He has a flair for clever terms. He pointed out, as an example, the split between the “commie corridor”, running from Park Slope to another area to Astoria, where he forecasted (correctly) that the left-wing candidate would win by huge margins, and the conservative-leaning zone on Manhattan’s Upper East and Upper West Sides. In those areas, certain media outlets and Wall Street Journal outrank the mainstream paper” in audience and the majority of electors favored the independent, who ran as a moderate alternative.

Voting Day Patterns and Unexpected Results

What was your night?

I had to do that because they were adding approximately 200K ballots into the system every few minutes! I felt somewhat anxious at the beginning: Mamdani led the early vote by 12 points, but came two big batches of votes that came in later and the advantage went from 12% to 8%. I was worried.

Understand, there was a world where yesterday turned out somewhat badly for Mamdani, in which the opponent would have basically doubling his votes from the Democratic primary. However the winner added 500,000 supporters to his primary coalition, and that’s a huge reason why he won. He campaigned and massively expanded his base from the primary.

Coalition Building

Where did the mayor-elect get additional support from?

He built the alliance that the left always wanted to build: it’s multiracial, youthful, tenants and individuals squeezed by affordability. He gained significantly with minority communities, working- and middle-class voters, compared to the primary. Additionally he further maximized his core of liberal progressives, youthful radicals, and Muslims and south Asians. He couldn’t have won without making those significant inroads.

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

It is a real thing, limited to working-class Latinos, south Asians and Islamic voters. Electors in immigrant strongholds that supported Trump last year backed Zohran this year. However I wouldn’t say he was winning over white working-class voters and Trump loyalists.

Turnout and Impact

A major development of the night was the sky-high participation. Who benefited?

Each candidate. Participation was significantly higher than I had expected. I thought it could exceed two million, but it reached 2.3M – that is a huge number of participants. Existed a decent opposition group, energized, but his supporters was also motivated, and that sufficed to win.

You predicted he’d exceed 50% of the vote. Is he likely for that?

Currently it appears he’s likely to surpass 50%. He has just over 50% but remain around 200,000 votes left to report at that time. So it’s not it’s definitive, but I think probable, and I hope he does because afterwards no one can say the Republican was a disruptor.

GOP Decline

The GOP candidate, the conservative contender, was another surprise. His support plummeted.

He didn’t win any district in any area. Including Tottenville in Staten Island, similar to an 88% Trump area. That really was unexpected. Cuomo kept very white areas, affluent zones and very religiously Jewish areas, and plus gained many conservatives on Staten Island with a high participation. I believe there was significant strategic balloting by the Republicans. They were doing it before Trump tweeted his support for Cuomo, but that definitely helped. It might have changed the outcome if Mamdani’s coalition hadn’t grown.

The “Commie Corridor”

Regarding your often-discussed “commie corridor” – did backing for Mamdani dominant in those parts of Brooklyn and Queens?

I think existed some weakening of the commie corridor in some areas like Astoria or Greenpoint that have older Caucasian residents. In Astoria, for example, the property owners and homeowners supported the independent. So there existed a little resistance. However overall, mostly the leftist base is another huge reason why Mamdani won – he scored between 77% and 83% in specific neighborhoods.

Jewish Voters

In the lead-up to the vote we reported on if the candidate was gaining ground with Jewish New Yorkers. Any indication that he succeeded?

Exist areas with many non-religious and left-inclined voters – like Park Slope and Morningside Heights – where he did well. However in the affluent districts like the Manhattan area, his Middle East stance was influential there. Likewise in the more middle-class Jewish areas including Queens neighborhoods, or Bronx areas – they favored Cuomo. Plus, there are Jewish immigrants from Eastern Europe in southern Brooklyn, who were strongly Cuomo. Therefore I don’t know if there were major surprises on this one, but he retained more progressive Jewish neighborhoods and including sections of the another locale with large leads.

Long-Term Significance

Has Mamdani rewritten what New York represents in politics? Will commie corridor serve as a springboard for progressive contenders?

Yes, it’s no coincidence that some of the biggest figures from the left hail from a few areas in the boroughs. I believe that there will be more of that – candidates will emerge from these areas to be promoted to higher office.

But I think that each urban center in America can have their own commie corridor. Urban places are the epicenters of leftwing power in America – since they’re young, people rent and they represent locales where people are crushed by the disparities we face.
