ALBANY – Sixty-four percent of New Yorkers give Gov. Andrew M. Cuomo a sour rating of his job performance, the lowest since he became the state’s chief executive in 2011, a new poll has found.

Among upstate residents, 72 percent gave Cuomo a negative job rating, the Siena College poll says.

The poll, released Monday morning, also found his overall approval rate at its worst level: 50 percent of respondents in one of the nation’s most Democratic states view the Democratic governor unfavorably. (Forty-three percent viewed him favorably and 7 percent had no opinion.)

“Politically, Cuomo’s ratings drop is across the board, as he fell with Democrats, Republicans and independents. Geographically, his drop was much bigger downstate – New York City and the suburbs – than upstate, where his ratings were significantly lower previously,” said Siena poll spokesman Steve Greenberg.

Beyond Cuomo, the poll found that U.S. Senate Minority Leader Charles Schumer is not standing well with New Yorkers at the moment. Schumer scored well with residents before becoming the U.S. Senate’s top Democrat, including many Republicans, but he has slid since then. In the new poll, he is viewed favorably by 47 percent of New Yorkers, and unfavorably by 46 percent.
