New York: How to vote, where to vote and what’s on the ballot.

New York has several primaries for statewide office on Tuesday, including for governor and lieutenant governor. Some State Assembly districts also have primaries. Here’s what to know:

How and where to vote

New York has closed primaries, meaning that you have to be enrolled in a party to participate and you cannot vote if you’re an independent. Early voting ended on Sunday, but polls are open on Tuesday from 6 a.m. to 9 p.m. statewide.

You can check whether you are registered with a party, and the location of polling sites, through the state board of election website.

What’s on the ballot

Several statewide offices are on the ballot this year, including for governor, where the incumbent Democrat, Kathy Hochul, is facing Jumaane D. Williams, the New York City public advocate, and Representative Thomas R. Suozzi of Long Island.

On the Republican side, Representative Lee M. Zeldin — the party’s anointed candidate — is being challenged by Rob Astorino, the former Westchester County executive; Harry Wilson, a corporate turnaround specialist; and Andrew Giuliani, the son of the former New York City mayor Rudolph W. Giuliani.

The newly appointed lieutenant governor, Antonio Delgado, a Democrat, is also being challenged in the primary by Ana María Archila, an activist who gained national attention when she confronted Senator Jeff Flake of Arizona during the hearings over the Supreme Court nomination of Brett Kavanaugh. A third candidate, Diana Reyna, is a former New York City council member and running with Mr. Suozzi.

Mr. Zeldin’s running mate, Alison Esposito, is running unopposed on the Republican side.

The ballot also includes primary races for the State Assembly, the lower chamber of the Legislature, which is controlled by Democrats. All 150 seats are up for grabs in the fall, though not all members face primary challenges.

In the Democratic Assembly races, a slate of left-leaning candidates are challenging a number of established members.

They aim to push Democrats to commit to progressive agenda items — such as climate bills, including one allowing the state to build publicly owned renewable energy projects — or defeat them by focusing on those issues.
