More than 730,000 New Yorkers have already cast ballots ahead of tomorrow's mayoral election

more than four times the number that voted early four years ago.

It's a race with big stakes for the city and beyond.

Democratic Socialist Zoran Mamdani has vaulted from a relatively unknown state legislator

to the frontrunner to lead the largest city in the country.

William Brangham reports on what his potential victory means for New York City and the larger

Democratic Party.

At a packed concert venue in Queens recently, thousands of supporters gave Zeran Mamdani the rock star treatment.

Momdani joked about just how unlikely his meteoric rise was.

As recently as this February, our support had reached the eye-watering heights of 1%.

We were tied with noted candidate, someone else.

But today, he is the frontrunner to be New York's next mayor after winning a crowded

Democratic primary with his charismatic, relentlessly on-message campaign about affordability.

No New Yorker should ever be priced out of anything they need to survive.

His supporters are all in.

What is it going to be like in the future when we want to raise families, when we want to do whatever else?

And it's important that there's like a groundwork for that, which currently right now is a little shaky.

We want the city more affordable. We want, you know, people to have be fed. We don't want

ice on the street. Like these are all things. And I don't know if I trust in other candidates

to be able to do those things.

It feels like change and it feels like this is a hope for change for the better.

The 34-year-old Democratic Socialist is leading most polls by double digits.
