From the Morning Memo:

Gov. Andrew Cuomo has endorsed the Democratic challenger to Republican Sen. Phil Boyle in what is expected to be a competitive Senate race in Suffolk for the 4th district.

Boyle has drawn former Suffolk County Legislator Lou D’Amaro in the race for the seat, with the campaign being rolled out on Wednesday.

“It’s critical we elect strong, qualified leaders like Lou D’Amaro to the State Senate to fight for priorities critical to Long Island, including preserving the successful property tax cap, continuing to invest a record amount of funding in our schools, ensuring the safety of our students and fighting Trump’s disastrous repeal of state and local deductibility,” Cuomo said in a statement.

Democrats are trying to gain a working majority in the state Senate in the upcoming November general elections. Republicans hold a one-seat advantage in the 63-member Senate with the aid of Sen. Simcha Felder, a Democrat aligned with the GOP conference.

To be successful, Democrats will have to be competitive for seats in the Hudson Valley north of New York City and suburban districts on Long Island.

Cuomo, meanwhile, has faced pressure from the left to help the party gain control of the chamber. He helped forge a unity agreement earlier this year that led to the dissolution of the Independent Democratic Conference, while also pledging once again to aid candidates in battleground seats.

A source on Wednesday said Cuomo held a 40-minute phone call with D’Amaro to discuss the race and why he needed to run, with the governor pledging to help in the district.

“I am running for State Senate because we need someone who will actually fight back against the extreme Washington agenda and change the culture in Albany,” said D’Amaro. “Suffolk residents deserve a fighter who will take on the special interests, and I look forward to working with Governor Cuomo to deliver on these important issues.”
