Mr. Albanese, a Roman Catholic, met with several rabbis on Friday.

“Any candidate looks for places where he can campaign with the greatest number of people in the shortest time,” said Simcha Felder, the Democratic state senator whose Brooklyn district includes many Orthodox voters. “And that’s the opportunity of the Catskills.”

Unlike other portions of the diverse, and fragmented, New York City electorate, the Orthodox Jewish community is often believed to vote in a solid bloc. Indeed, several visitors at a camp attended by Satmar Hasidim said that they would simply vote for whoever they believed was favored by the United Jewish Organizations of Williamsburg, a social service organization that is influential in the community.

Not that individual issues weren’t on some people’s minds here, including what some Orthodox feel is either city interference — or indifference — to their community.

Solomon Katz, 28, a Satmar Hasid from Williamsburg, said he was upset about a 2012 decision by city health officials to require parents to sign consent forms acknowledging health risks for a type of ritual circumcision, known as metzitzah b’peh, in which the circumciser uses his mouth to remove blood from the incision. At Camp Skwere, several men pressed the candidate on financial support for religious schools, something Mr. Albanese said he worried might breach the wall between church and state. And Eva Tannenbaum, 35, of Williamsburg, pressed Mr. Albanese on a common concern in Orthodox neighborhoods.

“One thing: housing, housing, housing. There is no housing,” Ms. Tannenbaum said.

Mr. Albanese, who visited about a dozen locations during his two-day tour, seemed to draw curious looks in most camps: a khaki-wearing, brochure-wielding candidate in a place where most adults were dressed in black and where religious texts are the preferred reading material.

Mr. Albanese’s wife, Lorraine, also drew some attention, smartly outfitted in a red seersucker jacket, beaded sandals, and Ray-Ban sunglasses.

At Village Park Bungalows, a camp with several generations of Orthodox regulars, Mr. Albanese walked up to a group of several women who were chatting and quickly got a rundown on their concerns, including schools and health care.
