NYC Mayor Zohran Mamdani’s hand-picked candidate for a City Council seat representing Greenwich Village is proving that socialism looks a whole lot better from a $6 million Westchester manor and a $3.7 million Chelsea condo, critics told The Post.

Lindsey Boylan — a former senior aide to ex-Gov. Andrew Cuomo who was the first woman to publicly accuse him of sexual harassment — joined Mamdani as a member of the Democratic Socialists of America last year while campaigning to help him defeat her ex-boss. Cuomo has denied any wrongdoing.

Boylan is married to investment banker LeRoy Kim, and lives with him and their daughter in a lush five-bedroom home in ritzy Bedford, NY.

During a Bedford zoning board of appeals meeting in December, Boylan whined about spending “thousands of dollars a month on landscaping” alone for the pristine property while seeking approval for a new deck.

Boylan, 42, and her family have also long lived in a swanky Chelsea condo valued at $3.7 million.

Kim is a deep-pocketed managing director of boutique investment banking firm Allen & Company, which notoriously holds an highly exclusive conference in Sun Valley, Idaho, widely nicknamed “Summer Camp for Billionaires.

Critics were galled by what they described as Boylan’s brazen opportunism.

“America, what a country!” marveled a top NYC union leader. “Lindsey Boylan can re-brand herself the socialist darling of the left while retreating to a seven‑figure country house upstate. At least she’s temporarily creating jobs for her third failed run for office.”

The silver-spoon socialist has embraced much of Mamdani’s Israel-hating beliefs while campaigning for Council, bashing the Jewish state for “unacceptable mass killing of civilians and journalists” and calling the war in Gaza a “genocide.”

The remarks fly in the face of her past advocacy for Israel.

“I’m someone who has an unshakeable support for Israel,” Boylan told Jewish Insider in 2019.

Boylan previously lost two bids for elected office — in 2020 to replace Rep. Jerry Nadler (D-Manhattan), and in 2021 to become Manhattan borough president.

During her failed run to unseat Nadler, Boylan cozied up to Harold “Heshy” Tischer, a controversial Brooklyn Orthodox Jewish power broker and Republican firebrand who was convicted of fraud in 2013.

In a campaign-endorsement video Tischler posted on X, Boylan gushed about visiting Jerusalem with her family and declared her “love” for the Jewish community. She even accepted an invitation to someday travel back to Israel with Tischler.

Tischler is also a staunch critic of gay marriage — something that wouldn’t go over well in Manhattan’s 3rd Council district, where Boylan is running. The district includes the Stonewall Inn, widely considered the birthplace of the gay rights movement.

Boylan is seeking to fill a vacant seat previously held by Democrat Erik Bottcher, who was sworn in as a state senator in February.

Gay advocates have blasted Mamdani for endorsing Boylan because district voters have for more than three decades routinely elected gay candidates to the Council post.

Bottcher is backing his former top aide Carl Wilson, who is gay, to succeed him, as are many local Democratic club and City Council Speaker and occasional Mamdani foe Julie Menin.

Despite Boylan locking up Mamdani’s endorsement, the DSA has opted to stay out of the race. Instead, Boylan’s other main endorsements include the far-left Working Families Party.

Boylan dodged questions about her wealth and her stances on Israel, but issued a statement Friday saying she’s been “proud to stand with the LGBTQIA+ community” her “entire career, and will continue to do so in the Council — especially as we face federal attacks on gender affirming care for our trans siblings and youth.

“My campaign is about all the voters of this district — trans and queer people included — and building a city we can all afford to live in and be proud of,” she added.
