A new poll released a day before primary day has Queens Assemblyman Zohran Mamdani overtaking former Gov. Andrew Cuomo in the final round of ranked-choice voting in the Democratic mayoral primary election.

The Emerson College, PIX11 and The Hill poll shows a neck-and-neck race between Cuomo and Mamdani during the first round of ranked-choice voting, with Cuomo holding a narrow lead at 35% and Mamdani close behind at 32%.

Comptroller Brad Lander follows in third with 13%, City Council Speaker Adrienne Adams has 8%, and former Comptroller Scott Stringer stands at 3%. Around 4% of voters remain undecided.

But in a ranked-choice voting simulation conducted by the college, Mamdani ultimately defeats Cuomo 52% to 48% in the eighth and final round. It marks the first time Mamdani has come out ahead in the final tally of any Emerson poll.

“Over five months, Mamdani’s support has surged from 1% to 32%, while Cuomo finishes near where he began,” Spencer Kimball, executive director of Emerson College Polling, said in a statement. “In the ranked-choice simulation, Mamdani gains 18 points compared to Cuomo’s 12, putting him ahead in the final round.”

Since the previous Emerson poll in May, Mamdani gained 10 points in first-choice support, up from 22%. Cuomo rose only one point, from 34% to 35%.

Voter behavior also differs sharply based on when ballots are cast. Among those who voted during New York City’s early voting period, Mamdani leads Cuomo 41% to 31%. But among those who plan to vote on June 24 or had not yet voted at the time of the poll, Cuomo holds a slight advantage, 36% to Mamdani’s 31%.

The survey was conducted from June 18 to 20 among 833 registered New York City voters. The poll's margin of error is +/- 3.3 to 3.6 percentage points.

Cuomo, who is also running on the independent Fight and Deliver Party line, has said he intends to remain in the race through the November general election regardless of the outcome of Tuesday’s Democratic primary.
