Trump Supporters Backing Mamdani and a Emerging Progressive Alliance: Key Unexpected Outcomes from New York’s Mayoral Race

Only two days prior to the New York mayoral election, political analyst Michael Lange issued a bold forecast – going beyond the winner citywide, but precinct by precinct. The analyst, an expert in elections born and raised in the city, has spent over a decade in progressive politics and emerged as something of a well-known figure recently for his deep dives into city data and polling.

He released his extremely precise prediction map – accurately predicting that Zohran Mamdani would win although failed to predict Andrew Cuomo’s solid showing – on his Substack, the Narrative War. Lange possesses a talent for clever terms. He highlighted, for instance, the split between the “commie corridor”, running from one neighborhood to Bushwick to Astoria, 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, “the Free Press and financial newspapers surpass the New York Times” in readership and the majority of electors favored the independent, campaigning as a conservative-courting independent.

Voting Day Trends and Surprises

What was your night?

I had to do that since they were adding approximately 200K ballots into the system every few minutes! I was actually a little nervous at the beginning: The candidate was ahead the early vote by 12 points, but came two big batches of votes that came in later and his lead dropped from 12% to 8%. I was worried.

Understand, it was possible in which election day went kind of poorly for Mamdani, where the opponent would have basically increasing his support from the Democratic primary. But the winner added 500,000 supporters to his initial base, and this was critical why he won. He campaigned and massively expanded his base from the first round.

Coalition Building

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

He assembled the coalition that the left long aimed for: diverse racially, youthful, it’s renters and it’s people squeezed by affordability. He improved significantly with minority communities, working- and middle-class voters, relative to the primary. Additionally he further maximized his base of liberal progressives, youthful radicals, and immigrant groups. He couldn’t have won without expanding his appeal.

He created the alliance that progressives always wanted to build: multiracial, young, tenants and residents squeezed by affordability

There were also a number of Trump/Mamdani voters – is this significant?

It is a real thing, limited to Hispanic laborers, Asian communities and Muslims. Voters in immigrant strongholds that supported Trump previously backed the progressive this year. But it’s not that he was gaining Caucasian laborers and Trump loyalists.

Turnout and Effects

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

Both sides. Participation was significantly higher than I had expected. I figured it could exceed 2 million, but it reached 2.3M – which is a lot of darn voters. There was a substantial anti-Mamdani block, who were motivated, but his supporters was equally driven, and that sufficed to win.

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

Right now it appears he’s favored to get over 50%. He’s at just over 50% but remain probably 200K ballots left to report as of Wednesday morning. Thus I don’t think it’s definitive, but I believe probable, and I hope he does because afterwards none can claim the Republican was a spoiler.

GOP Decline

Curtis Sliwa, the conservative contender, is the other big story. His vote plummeted.

He lost any district in any borough. Not even one neighborhood in the borough, which is like an highly conservative neighborhood. That truly was unexpected. Cuomo kept very white areas, affluent zones and devout communities, and plus gained many conservatives on the island who had a strong turnout. I think there was a lot of tactical voting by GOP voters. They were doing it before the former president endorsed for the candidate, but it assisted. It might have changed the outcome unless Mamdani’s coalition failed to expand.

Progressive Strongholds

What about your much mentioned left-wing base – did backing for Mamdani dominant in those parts of Brooklyn and Queens?

In my view there was some weakening of the commie corridor in certain places like neighborhoods that have older Caucasian residents. In Astoria, instance, the property owners and homeowners all went for Cuomo. So there existed some opposition. However overall, largely the leftist base is another huge reason why Zohran prevailed – he scored between 77% and 83% in specific neighborhoods.

Jewish Voters

In the lead-up to the vote there was coverage on if Mamdani was gaining ground with the community. Is there any suggestion that he succeeded?

There are neighborhoods with a lot of non-religious and left-inclined voters – such as Park Slope and Morningside Heights – where he performed strongly. However in the affluent districts such as the Manhattan area, his Middle East stance was influential there. Similarly in the moderate communities like Forest Hills, Rego Park, or Bronx areas – they favored the independent. Plus, you have Jewish immigrants from the former Soviet Union in southern Brooklyn, who were strongly supportive. Therefore I don’t know if there were crazy narrative-busters on this one, but Mamdani did hold more progressive Jewish neighborhoods and including sections of the another locale by big margins.

Political Impact

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

Yes, it’s not accidental that key figures from the left come from a few areas in Brooklyn, Queens and the Bronx. I believe that we’ll see additional examples – people will emerge from these neighborhoods to be elevated nationally.

However I believe that each urban center in the US could develop similar progressive hubs. Cities are the centers of leftwing power in the nation – since they’re young, tenancy is common and they are places where people are crushed by the disparities exist.
