ALBANY – Zohran Mamdani skipped the vote on the one bill he passed this year as a state lawmaker, The Post has learned.

The chronically-absent Mamdani didn’t bother visiting the state Capitol after New York’s budget was approved in May, The Post previously reported — as he cast aside his duties as an elected state Assembly member to campaign for New York City mayor.

While on the trail he missed the June 13 vote for his only piece of legislation that passed the Assembly this year, as first reported by the Albany Times Union on Thursday.

Instead, Mamdani was in the Big Apple announcing a cross endorsement in the primary race with city Comptroller Brad Lander as both Democrats angled for a boost from each other’s voters in a ranked-choice primary election.

The following day, he hosted a rally with fellow socialist Rep. Alexandria Ocasio-Cortez (D-NY).

Mandani’s legislation, a non-controversial bill that would extend enhanced public input requirements for certain regulatory decisions made by state agencies, was approved with only one vote against it in both the Assembly and state Senate.

The socialist pol missed more than half of the Assembly’s roll call votes this year, a feat made even worse given that the chamber allows members to vote remotely during situations such as “disability, illness, caregiving responsibilities, or any other significant or unexpected factor.”

His lone bill was sponsored in the upper chamber by state Senate Deputy Majority Leader Michael Gianaris (D-Queens).

Mandani’s campaign did not return a request for comment.

“Zohran became a top tier candidate for NYC mayor while maintaining a near perfect attendance record through the conclusion of the weeks-delayed New York State Budget,” a spokesperson for his campaign told The Post asked about his voting record in Albany earlier this year.
