Another New York state Democratic Party “tracker” is being accused of snooping on the family of a Republican candidate for Congress, The Post has learned.

State Sen. Jack Martins, who is running for Congress on Long Island’s North Shore, is furious that a Democratic operative sent a “friend request” to his 19-year-old daughter, Kaitlin, on Facebook.

“There are lines you don’t cross. Family members are off limits,” Martins said. “I don’t want someone coming out of the blue from the Democratic Party tracking my daughter. He’s out of bounds!”

The Democratic worker identified himself in the post as Adam Sommer.

There’s an Adam Sommer on Facebook with a bio that includes “tracker at New York State Democratic Party.”

Kaitlin moved to un-friend him when she realized who he was.

“When my dad decided to run for Congress, I was told opponents might come after our family. But it really creeps me out that some man was stalking me on Facebook trying to find something to use against my dad. It’s disgusting,” Kaitlin said.

Another Democratic tracker, Yougourthen Ayouni, was fired after The Post reported he allegedly stalked the family of a GOP candidate challenging Hudson Valley Rep. Sean Patrick Maloney.

Jessica Oliva, the wife of GOP candidate Phil Oliva, said she caught Ayouni peering into the windows of the family home in Westchester County.

Martins, who is running for the seat of retiring Democratic Rep. Steve Israel, cried foul over the tracker snooping on his daughter after reading what happened to the Oliva family.

Far from being isolated incidents, Martins claimed Democratic Party strategists are encouraging trackers to investigate rivals’ families.

“It’s part of their modus operandi,” he said.

A top Democratic official insisted the opposite is true.

“I question the veracity of the senator’s assertion as to who “friended” whom but in the [Democrats’] recruitment and training of trackers, contact with family members and spouses is strictly prohibited,” said state Democratic Party director Basil Smikle.
