His comments came after a Siena College poll showed declines in his favorability, job performance and reelection ratings.
When asked about the numbers, he said: "I don't know, I don't know what that means, I don't know how people can say you're doing a good job but the favorable goes down. So, you know, they do these polls all the time. To tell you the truth, I don't put too much stock into them. We're working very hard on the pandemic."
He added: "New York's success in dealing with COVID is inarguable ... I'm going to focus on my job. That's what I’ve always done, and you know public opinion goes up, it goes down, but if you're doing job and people respect the job you're doing, to me there's no more important barometer than that."
The numbers came amid a cloud of accusations involving alleged sexual harassment and scrutiny over his administration's reporting on nursing home deaths during the pandemic.
Cuomo also declined when asked to say how much money he made from his book about his leadership during the pandemic. Instead, he said the numbers would be released as part of his income tax returns.
"I probably am unique in the nation -- I'll give you something to play with. What public official in the United States has released more taxes -- personal income taxes -- for a longer period of time than I have," he said.
"I bet you I've released my personal income taxes for the past 20 years, and I will do that again this year. And you will see everything you want to see in the personal income taxes."
Only 40% of New Yorkers have a favorable opinion of Cuomo in the Siena College survey released Monday, with 52% saying they see their governor in an unfavorable light. That's down from 43%-45% in March and 56%-39% in February.
Cuomo's job performance in the poll, which was conducted April 11-15, stands at 42% approval and 56% disapproval. That's down from 46%-52% in March and 51%-47% in February. But a majority of New Yorkers – 51% to 37% – say Cuomo shouldn't resign, which is basically unchanged from a month ago. And by a 52%-to-38% margin, they say he can effectively do his job as governor, down from 48% to 34% in March.
According to the poll, 60% of New Yorkers approve of the job Cuomo’s doing handling the pandemic. But by a 44%-to-22% margin, they think the governor has committed sexual harassment, with just over a third undecided. Last month voters by a 35%-to-24% margin thought Cuomo had committed sexual harassment, with just over four in 10 undecided.
