Trump Supporters for Mamdani and a Emerging Progressive Alliance: The Biggest Surprises from New York’s Election

Only two days before the New York race for mayor, Michael Lange issued a significant electoral prediction – going beyond the winner overall, and block by block. Lange, a political analyst who grew up in New York City, devoted over a decade in progressive politics and emerged as a kind of well-known figure this year for his deep dives into city data and voter surveys.

He released his highly detailed prediction map – accurately predicting that the progressive candidate would win although missing the independent candidate’s strong performance – on his newsletter, the Narrative War. He possesses a talent for clever terms. He highlighted, as an example, the split between the “commie corridor”, running from Park Slope to another area to Astoria, where he forecasted (accurately) that the left-wing candidate would win by large leads, and the “capitalist corridor” on affluent parts of Manhattan. In those areas, “the Free Press and financial newspapers surpass the mainstream paper” in readership and most voters leaned toward Cuomo, campaigning as a conservative-courting independent.

Voting Day Patterns and Unexpected Results

How was your night?

It was necessary since they were adding approximately 200K ballots into the tally every few minutes! I felt somewhat anxious initially: The candidate was ahead the early vote by 12 points, but came large groups of ballots that came in after that and his lead dropped from 12% to 8%. It was concerning.

You know, it was possible in which yesterday went kind of poorly for him, where the opponent would have essentially doubling his votes from the Democratic primary. However Mamdani added half a million supporters to his initial base, and this was critical why he succeeded. He campaigned and massively expanded his support from the primary.

Expanding Support

How 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 squeezed by affordability. He gained significantly with Black and Hispanic voters, everyday New Yorkers, relative to the earlier election. Additionally he further maximized his base of liberal progressives, youthful radicals, and immigrant groups. Victory required without expanding his appeal.

He built the coalition that progressives long aimed for: diverse, young, tenants and people struggling with costs

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

It’s definitely a genuine phenomenon, confined to Hispanic laborers, south Asians and Muslims. Electors in ethnic enclaves that supported the former president previously went for the progressive now. However it’s not that he was gaining white working-class voters and Trump loyalists.

Voter Participation and Impact

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

Each candidate. Participation was much greater than anticipated. I figured we might exceed two million, but it’s closer to 2.3M – that is a lot of darn voters. There was a substantial opposition group, who were motivated, but the Mamdani base was equally driven, and that was enough to win.

You forecasted he’d get over 50% of the vote. Is he likely for that?

Right now it appears he’s favored to surpass 50%. He’s at just over 50% but there’s still around 200,000 votes uncounted at that time. Thus I don’t think certain, but I think probable, and I wish he achieves it so then no one can say the Republican was a spoiler.

Republican Collapse

Curtis Sliwa, the Republican candidate, was another surprise. His vote plummeted.

He lost a single precinct in any borough. Including one neighborhood in the borough, which is like an highly conservative area. That truly surprised me. Cuomo held Caucasian districts, affluent zones and very religiously Jewish areas, and then added all of these conservatives on Staten Island who had a high participation. I think occurred significant tactical voting by GOP voters. This happened before the former president endorsed for Cuomo, but that definitely helped. It could have even turned the tide unless the winning alliance failed to expand.

Progressive Strongholds

Regarding your often-discussed “commie corridor” – 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 some areas like Astoria or Greenpoint that have older Caucasian residents. In Astoria, for example, the Greek landlords and homeowners supported Cuomo. Thus there existed some opposition. But overall, mostly the leftist base is a key factor why Mamdani prevailed – he scored between 77% and 83% in specific neighborhoods.

Community Support

Prior to the election we reported on whether the candidate was making inroads with Jewish New Yorkers. Is there any suggestion that he succeeded?

There are neighborhoods with a lot of non-religious and left-inclined voters – like specific locales – where he did well. However in the affluent districts like the Upper East Side, his Middle East stance definitely mattered in those places. Similarly in the moderate communities like Queens neighborhoods, or Spuyten Duyvil and Riverdale – they favored Cuomo. Plus, there are newcomers from Eastern Europe in southern Brooklyn, they were pretty staunchly supportive. So it’s unclear if there were major surprises here, but Mamdani retained left-leaning areas and including sections of the Upper West Side with large leads.

Political Impact

Did Mamdani redefine what New York means politically? Will progressive base serve as a springboard for leftwing candidates?

Yes, it’s not accidental that key political leaders from the left come from a handful of neighborhoods in Brooklyn, Queens and the Bronx. I’m sure that there will be additional examples – people will come from these areas to be elevated nationally.

But I think that each urban center in the US can have similar progressive hubs. Cities are the centers of progressive influence in the nation – since they’re young, tenancy is common and they represent locales where people are crushed by the disparities we face.
