An ex-NYPD lieutenant who supported Republicans for years has changed his tune and is now singing the praises of Mayor Zohran Mamdani as he seeks a lefty state assembly seat.

Shamsul Haque is hopping onto the Mamdani bandwagon — showering the Democratic Socialist New York City mayor with praise — even though he and his Bangladeshi political group previously vehemently attacked such woke politicians and supported GOPers for years.

“My group will vote Republican this November,” Haque’s organization “Rise Up New York City” posted to X in February 2022.

New York City Zohran Mamdani and his socialist pals have peddled woke anti-capitalist views for years.

That same year, “Rise Up,” commenting on a photo of Democratic Socialists of America officials including Mamdani, wrote, “This team will ruin NYS.”

Haque and “Rise Up” supported and even campaigned alongside Brandon Castro — the Republican candidate for the 30th Assembly District seat he’s now running for himself — in 2024.

Since founding the group five years ago, Haque has posted numerous similar comments online about lefty politicians and groups such as the DSA and Working Families Party.

“When water, heating bills, and property taxes are going up, how do you expect a rent freeze?” Rise Up posted in 2023, responding to the the Working Families Party demanding a rent freeze.

“Your party has caused pain and suffering to working-class New Yorkers. Your party has supported extremist candidates in NYS,” Haque claimed.

Rise Up’s X account also tweeted to DSA state Sen. Jabari Brisport (D-Brooklyn) in 2022, “Sometimes I wonder who is worse for our nation: Trump or DSA.”

But since declaring his assembly candidacy earlier this year, Haque has sharply pivoted toward supporting Hizzoner, including by hiring his election lawyer and associate, Ali Najmi.

Haque and his group usually favor Republicans.

“DSA is unequivocally in favor of taxing the rich, and I am in the same boat,” he told City & State New York in an interview after he announced his candidacy.

“They want to help the working-class people, and I’m in the same boat because I, too, come from the working class,” he said.

Fewer than three years ago, Haque was on X railing against state Sen. Mike Gianaris (D-Queens) for helping lead the resistance to a bid to have Amazon locate its new headquarters in the borough.

Haque and his group campaigned with Republican assembly candidate Brandon Castro for the 30th District in 2024.

“Capitalism isn’t perfect; but, when you compare it with socialism, it is 100 times better,” Haque wrote.

“For the sake of our state, please resign from senate immediately,” he told Gianaris.

Gianaris announced earlier this year that he would not seek reelection, leading Assemblyman Steve Raga (D-Queens) to announce his bid for the state senate seat, thus opening up his 30th District assembly spot for contenders such as Haque.

Queens Democrats are backing one of Haque’s opponents, Patrick Martinez, the son of a longtime City Council aide and nephew of former borough Dem boss Rep. Joe Crowley.

Nepali Community leader Somnath Ghimire is also running.

Raga easily defeated Castro by over 30 points in the heavily Democratic district in 2024.
