Beyond the three Democratic congressional primaries in the city, there’s a slate of contested legislative primary races in all the boroughs, except Staten Island.

Registered Democrats in four of the five boroughs are heading to the polls.

There are 16 Democratic primaries for the state Assembly, one Republican primary for state Assembly in Queens and a Democratic primary for a state Senate seat spanning Manhattan, Brooklyn and Queens.

Some of the competition stems from the impending retirement of some veteran lawmakers.  

Like Jeffrion Aubry of Queens’ 35th district, covering the neighborhoods of East Elmhurst and Corona, and Helene Weinstein in Brooklyn’s 41st district, spanning Midwood and Sheepshead Bay.

In Harlem, Inez Dickens’ exit sparked a competitive four-way contest that’s pitting the establishment-backed candidate against insurgents.

On the Upper West Side and Morningside Heights district, five candidates want to succeed Danny O’Donnell.

“That’s a very high turnout area [on] the West Side of Manhattan. I probably give the edge to Micah Lasher. Just because [of] the weight of many of these endorsements, Mike has been around for a long time,” political consultant Trip Yang told NY1.

Meanwhile, some incumbents are fighting for their political lives.

Freshman Juan Ardila, who represents Sunnyside and Ridgewood in Queens. has failed to clinch meaningful endorsements or fundraise, following a sexual harassment scandal.

In the 40th district, Ron Kim faces headwinds.

“What this race is really going to show is, how in a district that’s over 70% Asian American, do Asian Americans care about the candidate who most leans on public safety and accountability, from their perspective?” Yang said.

Formerly a proponent of the “Defund the Police” movement, Kim has pushed for more cops in the subways.

But Yi Andy Chen got the powerful police unions’ endorsement.

Advocacy group Open New York also said it is backing Chen.

“This challenger was a marked improvement in housing policy over the incumbent,” Annemarie Gray, the executive director of Open New York, said, telling NY1 Chen received the group’s endorsement because they were unhappy with Kim’s housing track record.

“This is a district where people are really struggling with housing and we really need to see someone who is taking the problem more seriously,” Gray said.

“After they’re elected, there’s a lot of work to do and we’re gonna be holding them accountable to that,” she continued.

Meanwhile, some moderate Democrats are trying to fend off challenges to their left. Incumbent Stefani Zinerman is being out fundraised by Democratic socialist Eon Huntley, despite getting the backing of House Minority Leader Hakeem Jeffries and state Attorney General Letitia James.

Yang said the races often deal with hyper-local issues and dynamics.

Upsets could happen, given typically low turnout.

“Talk about what’s going on in the neighborhood. It’s important to build your own independent brand,” he argues. “You have to be separate from a mayor, a governor, or a sitting president because ultimately voters in a Democratic primary, they’re not voting between Joe Biden and Donald Trump. They’re voting between you and another Democrat.”

Republicans have just one primary to watch out for in Queens’ 25th district — the seat held by Democratic Assemblywoman Nily Rozic.

And there’s just one Democratic primary for the state Senate — incumbent Kristen Gonzalez, whose district spans three boroughs.
