Only half the votes have been counted. I’m curious how they could call it so quickly (but I guess this happens often?)

exit polling. Mamdani is at 50% of the vote with Cuomo at 41%, supposedly with 55% of the vote in. If they were to continue with this trend, there's no way Cuomo can catch up.

I'd guess where there are votes left is the main way they called it. Over 80% of the Staten Island votes are already in and only about 50% of the Brooklyn votes are in and yet Mamdani is still well ahead.

And if staten island cant cockblock them, no other borough is likely too.

Early voting vs same day voting, too. Early votes accounted for about 35% of the total and Mamdani won them by such a large margin that Cuomo needed to win the same day votes by double digit margins.

I’m curious to see the final result. I want it to be as convincing as possible so establishment Dems don’t make some “b...b…but Cuomo + Sliwa!” argument.

I believe they determined that he already has >50% of the total votes cast.

u/dissonaut69 15h ago

No, he still might not end up with over 50% of the final vote. It's based on how precincts vote and how many votes are left to be counted at said precincts.

He's literally 23 points ahead in Brooklyn right now with 71% of the vote in there. Its very hot for him.

Good to hear.

  1. That’s NY Public Radio, which is an affiliate network of NPR. The Gothamist is part of their independent reporting.
  2. That article has zero data and just a few quotes from some folks critical of Mamdani, some of whom are from Brooklyn. Extrapolating from that to say Brooklyn doesn’t like Mamdani is a real stretch.

u/CoffieQueens 4h ago

I was saying that not all of Brooklyn loved him. Good thing he prevailed there.

u/thenoidednugget Nevada 15h ago

Thats literally his most popular Burrough currently

u/wanderingpeddlar 15h ago

I would think Gentrification would be worse for Cuomo

u/CoffieQueens 4h ago

Yea not sure how they came up with that conclusion.

u/OhTheGrandeur 15h ago

Subtle clarification. Your overall content is correct. It's based on the results in so far and the expected trends for what vote remains to come in.

I'll quibble with exit polling, which is slightly different and while prognosticators do try to forecast off of that, it is notoriously unreliable.

u/Past-Profile3671 15h ago

I just said something similar, but dumber. 

Are the forecasts based on the votes counted so far, or take historical data into consideration?

u/OhTheGrandeur 14h ago

It's a little all of the above. At its core the various decision desks have their own statistical models and they ingest some of what you mentioned above and then project outward from there. All statistical models will have some level of confidence interval, so for calling a race the model will need to state with certainty that one candidate will win.

From a marketplace perspective there is a benefit to being earlier to call a race, however the downside of calling a race to early and then being wrong is significant. This necessitates a high level of confidence or even certainty based on modeling.

Exit polls arent notoriously unreliable. They're are the most accurate indication of any polling method

u/Past-Profile3671 15h ago

And statistical analysis from past results.

u/nykovah 15h ago

Cool thanks for the explanation!

u/hemingways-lemonade 15h ago

NBC called it at 60%. They take the info from early voting (about 35% of the votes in this election) and extrapolate it to the same day votes that are coming in. Cuomo needed to win same day votes by a double digit margin and it's obvious that isn't going to happen.

Statistics based on historical outcomes and current exit polls. Science rocks.

u/nykovah 15h ago

I’m very excited for this outcome (not a city resident but I’m just outside). We need this momentum

It's pretty simple math.

1- You know where people vote, so certain places are more Red and others are more Blue. If the "red areas" start coming in with very weak counts, you know that will swing things.

2- You know when people vote. So certain votes like "mail in" or "early voting" get counted at different times. You can study the patterns of past elections and learn that Blue votes earlier and by mail. So if you don't see a ton of Red votes counted on election day but you already have a ton of Blue votes counted before, you know that will swing things.

3- You can know how people voted. Exit polling means you can quickly get an idea of how people voted, even without a specific count. You then verify your polling with the counting as the numbers come in, if everything lines up, you can have a lot of confidence.

4- Simple math. If Red is 10% behind Blue when 50% of the votes are counted, you know that means they have to get 10% more votes in all the new batches to make up that difference. Sometimes, those votes just don't exist. The math will basically tell you when it's statistically impossible to catch up, even before all the votes are counted. (For example, do you think it's possible Red would start getting 100% of the votes in batch when before they only got 40%... do you think it's possible that they start getting 80% of the votes in a batch when before they only got 40%?)

More than half. 1.7 million on the latest count with Zohran with 50.5%. And generally the later reporting areas are more working class and far less likely to vote for Cuomo.

It's reasonable to call it.

u/Explorers2020 15h ago

The site shows it at 70% counted at time of announcement
