Gov. Andrew Cuomo leads his Republican opponent Rob Astorino by 20 percentage points, according to a Quinnipiac University poll released on Wednesday morning.

The poll found Cuomo receives the support of 51 percent of voters polled compared to Astorino’s 31 percent. Howie Hawkins, the Green Party candidate, received 9 percent.

Without Hawkins in the race, Cuomo leads 55 percent to 34 percent.

Cuomo’s lead in the August Quinnipiac poll was wider, when the governor led Astornio 56 percent to 28 percent. Hawkins was not included in that poll.

Quinnipiac’s news release on the poll points to Cuomo’s 32-percentage point lead among women voters.

“New York Gov. Andrew Cuomo got a head start on the Quinnipiac University poll with his weekend campaign bus ride touting women’s issues. A monster lead among women voters powers him past Westchester County Executive Rob Astorino,” said Quinnipiac’s Mickey Carroll. “It ain’t over ‘til it’s over, but more than two-thirds of voters say their minds are made up.”

Indeed, Cuomo has a large advantage with women as he promotes his support for the passage of the full women’s agenda. But the last time Quinnipiac polled the race for governor in August, Cuomo had an even larger lead among women, with a 38 percentage-point difference separating him and Astorino.

Nevertheless, Astorino has some work to do not just with women, but in the overall favorability department.

Cuomo’s favorable rating is at 50 percent, with 39 percent of voters holding an unfavorable opinion of him.

Astorino, meanwhile, is underwater: 27 percent hold a favorable view of him, while 29 percent do not. Forty-three percent of voters don’t know enough about him to form an opinion, the poll found.

Cuomo continues to hold a wide fundraising advantage over Astorino, and the state Democratic Committee has been used a surrogate to blast the Republican nominee in a series of negative ads on television.

In the race for attorney general, Democratic incumbent Eric Schneidermans leads Republican John Cahill 46 percent to 34 percent.

And in the comptroller’s race, Tom DiNapoli, the Democratic officeholder, leads his Republican challenger 56 percent to 28 percent.

The poll of 1,153 likely voters was conducted from Oct. 1 through Oct. 6. It has a margin of error of 2.9 percentage points.
