Every state legislative seat in New York is on the ballot this year. Only a small handful of these races are competitive.

The 63 seats in the state Senate and 150 in the Assembly run for two-year terms, so they come up for a vote every two years. Of these, 27 Senate districts and 65 Assembly districts are in or overlap with New York City. More than half of these districts in the city have already been decided.

Twelve Senate and 35 Assembly candidates are running unopposed in heavily Democratic New York City, meaning the candidates — all but two of whom are Democrats — essentially ran their ticket in Albany after the primary election in June. Of the remaining neighborhoods, few in the city are expected to be close.

There are some notable exceptions, including the 17th Senate District in central and south Brooklyn, where first-term Democratic Sen. Iwen Chu faces a tough challenge from Republican Steve Chan, a former NYPD sergeant.

In the Assembly, Democrat-turned-Republican Alec Brook-Krasny is trying to hold onto his seat against Democrat Chris McCreight in South Brooklyn, while moderate Rep. Stacey Pheffer Amato is locked in a rematch with Republican Thomas Sullivan in Queens. Two years ago, she just beat him 15 votes.

Here’s a look at some of the key state legislative races in New York City this year.

17th Senate District

WHO: Senator Iwen Chu (Democrat, incumbent) vs. Steve Chan (Republican)

Where: Brooklyn, including Sunset Park, Bensonhurst, Bath Beach, Bay Ridge, Dyker Heights and Kensington

The debate: Chu, a former legislative staffer, first won a seat in the state Senate two years ago, winning her heavily Asian district by 534 votes.

Now, she’s running her record in her short time in office, where she’s made e-bike safety a big part of her platform. That includes getting an invoice approved, which requires sellers to affix a notice on all bicycles and electric scooters warning against riding on the sidewalk and reminding riders to obey all traffic laws, including yielding to pedestrians.

“How do we support our police? I have a record,” she said in an interview with Gothamist. “How do we prevent those e-bike fires or (promote) e-bike safety? I have legislation that is law now.”

But Chan is leading a tough-on-crime campaign that emphasizes his past service in the US Marine Corps and the NYPD.

Another major issue in the race: a proposed shelter on 86th Street for up to 150 homeless men, which caused major protests in Bensonhurst.

“The whole neighborhood is rising up against it because there are better options,” Chan said. He argues that the shelter “doesn’t have to be in a major corridor where small businesses operate.”

District 23 Assembly

WHO: Assemblyman Stacey Pheffer Amato (Democrat, incumbent) vs. Thomas Sullivan (Republican)

Where: Queens, including the Rockaways, Howard Beach, Lindenwood and Ozone Park

The debate: It doesn’t come much closer than Pheffer Amato and Sullivan’s 2022 race, when the Democrat won by the slimmest of margins.

This year, there is a rematch. And it is expected to be tight again.

Pheffer Amato has been in the Assembly since 2017. She positioned herself as a staunch ally of law enforcementand she spoke against it the city’s migrant shelter at Floyd Bennett Fieldjust across the border of her district.

Sullivan served in the U.S. Army Reserve and made the migrant crisis and the repeal of the state’s cash bail reforms a major part of his campaign.

46th Assembly District

WHO: Assemblyman Alec Brook-Krasny (Republican, incumbent) vs. Chris McCreight (Democrat)

Where: South Brooklyn, including Coney Island, Seagate, part of Brighton Beach, Fort Hamilton, Dyker Heights and Bay Ridge

The debate: Brook-Krasny has a long history in New York politics.

He was in the state Assembly as a conservative Democrat from 2007 until 2015, when he resigned to work for a medical testing company. In 2017, it was indicted on health care fraud and bribery chargesbut was found not guilty of fraud charges and the bribery charge was eventually dismissed.

Two years ago, he ran for the Assembly as a Republican and won, flipping what had been a blue seat.

He faces a challenge from McCreight, a first-time candidate who is the chief of staff to Democratic City Councilman Justin Brannan.

11th Senate District

WHO: Senator Toby Ann Stavisky (Democrat, incumbent) vs. Yiatin Chu (Republican)

Where: Queens, including parts of Astoria, College Point, Whitestone, Bay Terrace, Douglaston-Little Neck, Bellerose and Holliswood, plus Rikers Island.

The debate: The Staviskys are a Queens institution, Toby took over in 1999 after the death of her husband, Leonard, himself in the state Legislature for more than three decades. And the district is heavily Democratic-leaning, with nearly four times as many Democrats as Republicans.

But Republicans feel good about their candidate, Yiatin Chu, whose introduction to politics came as the founder of a group that fought former Mayor Bill de Blasio’s push to eliminate the entrance test for the city’s specialized high schools.

“I think he deserves a real retirement, number one,” Chu said of Stavisky. “And two, I think she’s out of touch with where the people in her district are. This district deserves someone with more energy, some fresh ideas that are more connected to where this district is politically.”

Stavisky, who chairs the Senate Higher Education Committee, says that’s nonsense. She touted her continued effectiveness, noting her successful effort to boost New York’s Tuition Assistance Program earlier this year. She also cited her efforts avoid tuition increases at SUNY and CUNY schools.

“The fact that my position was that we should increase (TAP) to keep students in New York State, that was a new idea,” Stavisky said. “That’s what keeps me going. I had an idea and it worked. That, to me, is just amazing.”

One local issue that could have an effect on the race: the city’s migrant shelter at Creedmoor Psychiatric Center, which is in the district and drew significant protests from residents.

Other contested races:

• Brooklyn Sen. Andrew Gounardes, a Democrat, faces a challenge from Republican Vito LaBella in the 26th District, which includes parts of downtown Brooklyn and Park Slope. LaBella was defeated by Iwen Chu in a nearby district two years ago.
• First-term Democratic Sen. Jessica Scarcella-Spanton of Staten Island is facing off in the 23rd District against Republican Marko Kepi.
• In the state Assembly, Republican Philip SC Wang, a chiropractor, is challenging Democratic Assemblyman Ron Kim in the 40th District, which includes parts of Flushing and Murray Hill.
