The poll found a three-way race shows 46% of likely voters support Mamdani, 33% support Cuomo, and 15% support Republican candidate Curtis Sliwa.
This compares to Quinnipiac University's poll on Sept.10 when it was a 4-way race with Mamdani receiving 45% support, Cuomo receiving 23% support, Sliwa receiving 15% support, and Adams receiving 12% support.
Adams dropped out of the race late last month. And it would appear that virtually all of his supporters are now backing Cuomo.
Many of them, Jewish voters once loyal to Adams.
"The one area where he is seeing a huge lead is among Jewish voters. And the fact of the matter is, Mamdani is still ahead by double digits," Assistant Quinnipiac Poll director, Mary Snow said.
Mamdani's is viewed more favorably than the others and his supporters are fired up.
90% of Mamdani's supporters are "enthusiastic" about their candidate. Compare that to 85% of Sliwa's supporters and 69% of Cuomo's supporters.
But graded on experience, 73% gave the edge to Cuomo, compared to just 39% for Mamdani and 24% for Sliwa.
Mamdani Thursday, tried to reassure many of the city's business leaders.
"What characterizes me in the way I'll lead this team is hiring the best and the brightest, empowering them, doing so always knowing that I hold the ultimate responsibility," Mamdani said.
Cuomo has a path forward if Sliwa's voters defect.
"The indications, though, in this poll is that no, they won't, because many of them are saying their minds are made up and they're enthusiastic about it," Snow said.
But, "the path is now clear," said Cuomo's campaign spokesman. "This is a two-person race with one month to go, a surge in fundraising, endorsements, and volunteers, momentum is building, with more to come," they continued.
The Cuomo campaign is banking on Sliwa's voters to ignore his name on the ballot. But the poll indicates that's not likely-especially with their candidate still in the race.
The poll was released the same day the Campaign Finance Board met and awarded a big payday to the candidates.
Cuomo was awarded $2,329,463 in matching funds, Sliwa is getting $1,158,547 and Mamdani is getting $1,029,721 -- although he has already raised enough to reach the spending cap.
The board once again denied matching funds to Adams as it continues to investigate his fundraising in the 2021 mayor's race.
The board will award its final matching funds on Oct. 30, the last meeting before the election.
