A 17-seat advantage over Republicans holds some tantalizing prospects for Democrats in the state Senate.

But there are also some pitfalls for a conference that will have lawmakers, 15 of them freshman, representing upstate, suburban and New York City Senate districts, all of which have competing needs.

It’s going to fall to the incoming majority leader, Sen. Andrea Stewart-Cousins, to manage the competing interests of the largest Democratic conference in more than a century.

“It’s something that we understand there are a lot of different issues and I always spend the time and the effort to examine the issues, the alternatives, to really be informed and also look at New York in its entirety,” she said in an interview on WCNY’s The Capitol Pressroom on Friday morning.

Stewart-Cousins herself represents a suburban Senate district in Westchester County. Her conference will grow in 2019 to 39, potentially 40 members, after spending the last decade in the minority and kept from power by an alliance between Republicans and the now-defunct Independent Democratic Conference.

“I also know that over the years we have understood more and more it’s a big place and each region really does require different things,” she said. “I’m a suburban legislator as well, so I’m always conscious of that dynamic.”

Gov. Andrew Cuomo, who secured a third term on Tuesday, has also been aware of the dynamic, subtly saying in interviews that Stewart-Cousins, he is sure, understands the complexity of the state and the need to strike a balance.

Democrats picked up eight seats on Tuesday, including historically Republican districts in the Hudson Valley and on Long Island. Democrats last flipped the Senate in 2008, but the majority was a short-lived one, and gains made on Long Island and in upstate New York were dashed in 2010 election.

The conference has virtually turned over entirely since then, and Democratic lawmakers now in power say the same mistakes won’t be made.

“To find a way to govern,” Stewart-Cousins said, “we’re going to have to have a way that respects everybody.”
