After a rough summer of mass transit trouble in New York City, Gov. Andrew Cuomo’s approval and favorability ratings are up in a Siena College released Friday morning.

The poll found Cuomo’s favorability rating has bumped up to 57 percent to 35 percent, a slight increase from a 56 percent to 37 percent rating last month.

His job performance remains negative, however, with 48 percent approving and 50 percent disapproving. Still, that’s up from last month, when he recorded a 43 percent to 55 percent job performance, the poll found. At the same time, that’s a 10 percentage-point jump after it was flat last month, due to his support from Democratic and independent voters.

More than half of voters, 52 percent, are prepared to re-elect the governor, who is seeking a third term next year. Forty-one percent would prefer a generic “someone else.” The margin is an improvement for Cuomo from July, when 48 percent of voters backed his re-election bid and 44 percent preferred someone else.

President Trump’s ratings in New York continue to tank, meanwhile. Trump has a negative 28 percent to 68 percent favorability rating, down from a 29 percent to 66 percent spread in September. His job performance rating has remained virtually flat at 23 percent approval to 77 percent disapproval.

Though Cuomo is not on the ballot this year, a referendum on whether to hold a constitutional convention is, and support for the measure appears to be dropping, the poll found.

Voters by a narrow 44 percent to 39 percent margin back a convention, which is down from a 45 percent to 33 percent last month. They are also split on the potential effectiveness of a convention. Forty-four percent believe it’s a unique opportunity to revise the state constitution. Similarly, 45 percent believe holding a convention would be “an expensive waste of time.”

Nearly half of voters — 49 percent — said they have heard nothing at all about the coming referendum for a convention, which is held every 20 years.

Labor unions, environmental groups as well as conservative organizations have opposed the convention, believing deep-pocketed interests would seek to gain control of the convention and strip hard-won benefits from the constitution.

The convention is backed by some good-government organizations as well as attorneys, who believe it is a chance to update the constitution and combat structural problems in state government.

Fifty-three percent of voters said they would oppose a convention that strips unions of collective bargaining rights and 49 percent would not back any efforts to allow for more development in the Adirondack Park, which has protected status in the constitution.

The poll of 789 registered voters was conducted from Oct. 1 through Oct. 2. It has a margin of error of 4 percentage points.
