Trump Supporters Backing Mamdani and a New Left Coalition: The Biggest Unexpected Outcomes from NYC’s Election

Only 48 hours before the NYC mayoral election, Michael Lange made a bold electoral prediction – going beyond who would win citywide, but block by block. Lange, an expert in elections who grew up in the city, devoted over a decade in left-leaning activism and emerged as something of a local celebrity this year for his deep dives into city data and polling.

He published his highly detailed forecast map – which correctly forecast that the progressive candidate was victorious although failed to predict Andrew Cuomo’s solid showing – on his Substack, the Narrative War. Lange possesses a talent for clever terms. He pointed out, for instance, the divide between the “commie corridor”, running from Park Slope to another area to a third locale, where he predicted (correctly) that the left-wing candidate would triumph by huge margins, and the conservative-leaning zone on affluent parts of Manhattan. There, “the Free Press and Wall Street Journal outrank the mainstream paper” in audience and most voters leaned toward the independent, campaigning as a moderate alternative.

Voting Day Patterns and Unexpected Results

What was your night?

It was necessary because they were dropping around 200,000 ballots into the tally every few minutes! I felt somewhat anxious at the beginning: The candidate was ahead the early vote by 12 points, but came large groups of votes that came in later and the advantage dropped from 12 to 8%. It was concerning.

Understand, it was possible where yesterday turned out kind of poorly for him, where the opponent would have essentially doubling his votes from the earlier contest. However the winner added 500,000 votes to his initial base, and this was critical why he won. He campaigned and greatly broadened his base from the first round.

Coalition Building

Where did Mamdani gain additional support from?

He assembled the alliance that the left always wanted to build: diverse racially, it’s young, tenants and individuals facing cost pressures. He gained considerably with minority communities, working- and middle-class voters, relative to the earlier election. Additionally he further maximized his core of left-leaning activists, youthful radicals, and immigrant groups. Victory required without expanding his appeal.

He created the alliance that progressives long aimed for: diverse, young, tenants and residents squeezed by affordability

There were also some Trump/Mamdani voters – is this significant?

It’s definitely a genuine phenomenon, confined to Hispanic laborers, south Asians and Islamic voters. Electors in ethnic enclaves that went for Trump previously backed Zohran now. But I wouldn’t say he was gaining Caucasian laborers and Maga voters.

Turnout and Effects

A major development of the night was the record turnout. Who benefited?

Each candidate. Participation was much greater than anticipated. I figured it could go over 2 million, but it reached 2.3 million – that is a lot of darn voters. There was a substantial anti-Mamdani block, energized, but the Mamdani base was equally driven, and that was enough to win.

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

Right now it appears he’s favored to surpass half. He has just over 50% but remain around 200K ballots uncounted at that time. Thus I don’t think certain, but I believe it’s likely, and I wish he does because afterwards none can claim Sliwa was a spoiler.

GOP Decline

Curtis Sliwa, the Republican candidate, is the other big story. His vote completely collapsed.

He didn’t win any district in any area. Not even one neighborhood in the borough, similar to an highly conservative neighborhood. That really was unexpected. The independent kept Caucasian districts, affluent zones and very religiously Jewish areas, and plus gained many conservatives on the island who had a high participation. I think there was a lot of tactical voting by the Republicans. They were doing it prior to the former president tweeted his support for the candidate, but it assisted. It could have even turned the tide unless Mamdani’s coalition hadn’t grown.

Progressive Strongholds

Regarding your often-discussed left-wing base – did backing for the candidate overwhelming in those parts of Brooklyn and Queens?

In my view there was a little dilution of the commie corridor in certain places like neighborhoods that have more older white ethnic folks. There, for example, the property owners and residents supported Cuomo. Thus there existed a little resistance. But no, largely the commie corridor is another huge reason why Zohran prevailed – he scored between high percentages in specific neighborhoods.

Community Support

In the lead-up to the election we reported on whether Mamdani was making inroads with Jewish New Yorkers. Any indication that he succeeded?

There are neighborhoods with many secular and more progressive-leaning Jews – such as specific locales – where he did well. But in the wealthy Jewish communities such as the Upper East Side, his position on Israel was influential in those places. Likewise in the moderate communities like Queens neighborhoods, or Spuyten Duyvil and Riverdale – they favored the independent. And also, you have newcomers from Eastern Europe in southern Brooklyn, they were strongly supportive. So it’s unclear if existed major surprises on this one, but he did hold left-leaning areas and even parts of the Upper West Side with large leads.

Political Impact

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

Absolutely, it’s not accidental that some of the biggest figures from the left hail from a few areas in Brooklyn, Queens and the Bronx. I believe that we’ll see more of that – people will emerge from these areas to be promoted to higher office.

But I believe that every city in the US could develop their own commie corridor. Urban places are the centers of progressive influence in the nation – because youth reside there, tenancy is common and they are places where individuals struggle by the inequalities we face.
