New York is a big place with often divergent interests, Andrew Cuomo said, in his first interview after reelection — and the newly elected State Senate majority needs to remember that.

“They need to think not just about their district but about the whole state,” he said.

Cuomo appeared to be signaling to his fellow Democrats not to consider themselves unbound by constraints, now that the party controls all three branches of government.

The State Senate, where Republicans have largely held sway for the last century, has traditionally been where liberal dreams put forth by the governor and Assembly go to die. Even when the Democrats have briefly controlled the chamber — for instance during the inglorious interregnum of 2009-2010 — they’ve been hobbled by their whisker-thin majority. With only one or two seats to spare, trouble-makers seeking to create their own power centers ground business to a halt or formed coalitions with the Republican minority.

But on Tuesday, the potential for that particular kind of mayhem changed, at least numerically.

Official election results are still being confirmed, but Democrats could end up with as many as 40 seats to the Republicans’ 23. Though that chamber is among the most gerrymandered in the entire country, demographics and anti-Trump political momentum appear to have finally overtaken the GOP.

Speaking on WNYC, State Senator Michael Gianaris, from Queens, outlined the "bottled-up" progressive agenda his agenda hopes to start working on in 2019. He said that in the wake of this week's error-filled Election Day, with voting machines failing left and right, he would like to begin the upcoming legislative session with a slate of election reforms. It would include early voting, same-day registration and more.

“We've had a majority that for too long has kept people from voting, because they thought it was in their political interest,” said Gianaris, the likely Deputy Majority Leader. “And one of the first orders of business I think we should take up is changing that.”

Priorities for many Democrats also include reforming rent regulations, spending more money on education and the MTA — and potentially increasing taxes on the wealthy to pay for it.

Cuomo, speaking on WVOX, similarly echoed the need for voting reform. He said his other top priorities include stiffening firearms regulations, codifying abortion rights and eliminating the massive donations that New York, uniquely, allows from opaque limited liability corporations.

“We need ethics reform, and there's no reason not to pass it,” Cuomo said. “There's no reason legislative jobs should not be full-time positions with no outside income.”

Cuomo for years has been calling for “comprehensive” reforms, while denigrating others’ proposals for preventing corruption as too incremental. But he has also refused to spend political capital to enact those reforms.

He is perhaps most notorious for empowering a special panel to investigate Albany’s scandal-ridden political culture — only to dismiss that panel nine months later.

That dismissal attracted the attention of federal prosecutors — and led to the indictment and conviction of top Cuomo aides Joseph Percoco and Alain Kaloyeros.

With an eye toward the incoming legislature next year, Cuomo urged Democrats to proceed cautiously. He said the newly elected senate majority should keep in mind that the state has moderates and conservatives, and not just liberals — and upstate and rural interests and not just urban downstate ones.

He said if the Democratic party were to drift too far left, it could suffer a pendulum swing that would mirror the Congressional Republicans' experience in this week's midterm elections.
