With Danny O’Donnell stepping down from the state Assembly after being in office for more than 20 years, it’s an open political season on the Upper West Side.

Although the district’s Republican primary was canceled, there is a five-way Democratic primary in the predominantly liberal 69th Assembly District.

“I’ve spent the better part of my career in government. I got my start as an aide to Congressman Nadler,” said Micah Lasher, who recently served as Gov. Kathy Hochul’s policy director.

He previously worked for Mayor Michael Bloomberg.

“I was director of policy for the state until January. Working on housing issues, mental health issues, the kinds of stuff that I want to fight for the legislature,” Lasher said.

Under Hochul, Lasher helped devise bail reform changes and the housing compact proposal — pitched to mandate suburban development, but ultimately failing.

Now, he’s against her pulling the plug on congestion pricing.

“I’m a long-standing supporter of congestion pricing and with enormous respect and affection for the governor, I think it’s a mistake to delay it,” he said.

The other candidates agree — except for Jack Kellner, a public health professional and former city Department of Health physician.

NY1 was unable to reach him for an interview, but his campaign website says the program “would not have been of benefit for our district.”

“The MTA cannot be trusted with huge amounts of taxpayer funds,” the statement on the website continued.

Melissa Rosenberg talked about subway crime and homelessness.

“I think some folks definitely do feel that the subway system feels a bit less than safe, especially women,” she told NY1. “I think addressing this issue with more of, kind of an urban design lens and a services lens would be the right direction, ensuring that we’re doing as much homeless outreach o in the subways.”

Rosenberg has worked as a housing and homelessness policy advocate, she’s also a member of the Manhattan Community Board 7.

She said she jumped into the race after being frustrated by the affordability and housing crisis as well as women’s rights.

“Seeing what’s going on on a federal level and now even more on the local level, around how women and my people in my life, my friends, are losing our rights,” Rosenberg said.

For the first time since 2002, it’s an open seat.

The outgoing Democratic Assemblyman Danny O’Donnell endorsed Northrup. He serves as the policy director for the Bronx Public Defenders.

“I’m a public defender. I’m an advocate. I’ve been going up to Albany to fight for change,” he told NY1. “I think we really need somebody for the 69th District who’s willing to push back on this governor.

“We need to take care of each other. And that starts with providing health care. So when we think about Medicare reimbursement, we think about distressed hospitals. We need to protect our hospitals in our communities,” Northup continued.

The district is also home to Columbia University, where pro-Palestinian protests erupted on campus this spring.

“I believe in the right to express yourself. We need to do it without expressing Islamophobia or anti-semitism — that’s unacceptable. Like students, you know, there’s a long history of students protesting and protesting peacefully. I am in favor of discourse,” Northrup said.

Carmen Quinones is president of the New York City Housing Authority’s Frederick Douglass Housing, where she’s lived since she was 14.

“I believe that the community policing needs to take place. We need to partner with our police departments. We are the ones that know what’s going on firsthand. We got our finger on the pulse,” she said.

Quinones also said she believes in “equal” education opportunities, telling NY1 that the public schools need more resources.

“I think the people need to start making the decisions,” she said.

The district covers parts of the Upper West Side, Manhattan Valley and Morningside Heights.

Early voting continues until Sunday, June 23. Primary Election Day is Tuesday, June 25.
