Just two days before the NYC mayoral election, Michael Lange issued a significant electoral prediction – not just who would win overall, and precinct by precinct. The analyst, an expert in elections who grew up in New York City, has spent over a decade in progressive politics and emerged as something of a well-known figure recently for his thorough analyses into city data and polling.

He published his extremely precise forecast map – accurately predicting that the progressive candidate would win while failed to predict Andrew Cuomo’s strong performance – on his Substack, his platform. He possesses a talent for clever terms. He pointed out, for instance, the divide between the “commie corridor”, stretching from one neighborhood to another area to a third locale, where he predicted (correctly) that Mamdani would triumph by huge margins, and the conservative-leaning zone on Manhattan’s Upper East and Upper West Sides. There, “the Free Press and financial newspapers outrank the mainstream paper” in readership and the majority of electors leaned toward the independent, who ran as a moderate alternative.

Election Night Patterns and Unexpected Results

How was your night?

I had to do that since they were dropping around 200,000 votes into the tally every few minutes! I was actually somewhat anxious initially: The candidate was ahead the initial ballots by a dozen percentage points, but came two big batches of ballots that came in after that and the advantage dropped from 12% to 8%. It was concerning.

Understand, there was a world in which yesterday turned out somewhat badly for Mamdani, in which the opponent was going to end up basically doubling his votes from the Democratic primary. However the winner gained 500,000 votes to his initial base, and that’s a huge reason why he won. He campaigned and greatly broadened his support from the first round.

Expanding Support

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

He assembled the coalition that the left always wanted to build: diverse racially, it’s young, it’s renters and individuals squeezed by affordability. He improved considerably with Black and Hispanic voters, everyday New Yorkers, relative to the earlier election. Plus he boosted his base of left-leaning activists, youthful radicals, and immigrant groups. He couldn’t have won without making those significant inroads.

He built the alliance that progressives long aimed for: multiracial, young, renters and people struggling with costs

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

It is a real thing, confined to Hispanic laborers, south Asians and Islamic voters. Electors in ethnic enclaves that went for Trump previously went for the progressive this year. But it’s not that he was winning over Caucasian laborers and Trump loyalists.

Voter Participation and Impact

A major development of the election was the sky-high turnout. Who did that help?

Both sides. Participation was much greater than anticipated. I figured we might go over 2 million, but it reached 2.3M – which is a huge number of participants. Existed a substantial anti-Mamdani block, who were motivated, but his supporters was equally driven, and that was enough to secure victory.

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

Right now you would say he’s likely to surpass 50%. He has just over 50% but there’s still around 200K ballots uncounted at that time. Thus it’s not certain, but I think it’s likely, and I wish he achieves it so then none can claim the Republican was a spoiler.

GOP Decline

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

He lost any district in any borough. Including Tottenville in the borough, which is like an highly conservative area. That really surprised me. Cuomo held very white areas, very wealthy areas and very religiously Jewish areas, and then added many Republicans on Staten Island with a high participation. I think occurred a lot of tactical voting by the Republicans. This happened prior to Trump 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”

What about your often-discussed left-wing base – was support for Mamdani dominant in those areas of Brooklyn and Queens?

In my view there was a little dilution of the commie corridor in some areas like neighborhoods that have more older white ethnic folks. In Astoria, for example, the property owners and homeowners supported the independent. Thus there was some opposition. However no, mostly the leftist base is a key factor why Mamdani won – he was polling between 77% and 83% in specific neighborhoods.

Jewish Voters

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

Exist neighborhoods with a lot of secular and more progressive-leaning Jews – such as specific locales – where he performed strongly. However in the affluent districts like the Upper East Side, his Middle East stance 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 Jewish immigrants from the former Soviet Union in the borough, they were pretty staunchly supportive. Therefore it’s unclear if existed crazy narrative-busters here, but he retained more progressive Jewish neighborhoods and even parts of the another locale with large leads.

Political Impact

Did Mamdani redefine what the city means politically? Will progressive base become a launch pad for progressive contenders?

Absolutely, it’s not accidental that some of the biggest political leaders from progressives hail from a handful of neighborhoods in Brooklyn, Queens and the Bronx. I believe that there will be more of that – candidates will emerge from these areas to be elevated nationally.

But I believe that each urban center in America could develop similar progressive hubs. Urban places are the centers of leftwing power in the nation – since youth reside there, people rent and they are places where people are crushed by the inequalities exist.
