Mayor Bill de Blasio's approval rating is taking a nosedive in the city as a growing scandal threatens to engulf his administration and the NYPD, according to our exclusive NY1/Baruch College poll, which also shows Governor Andrew Cuomo faring much better statewide. Grace Rauh filed the following report.

Mayor Bill de Blasio's poll numbers are suffering. His approval rating dropped 10 points from February to 48 percent. 31 percent of city voters say they disapprove of the job he's doing, and 19 percent say they are not sure.

Our exclusive NY1/Baruch College poll was conducted from April 5 through April 10, right when a big story was breaking about a federal investigation into the police department and the mayor's campaign fundraising. Two de Blasio donors, who also served on his inauguration committee, are said to be suspected of providing gifts to top police officials in exchange for favors.

"I am confident that we have done this correctly and appropriately and legally," de Blasio said Monday.

Our poll found that New York City voters are split over the state of the city. 45 percent say it's headed in the right direction, but another 45 percent say it's on the wrong track. 10 percent are not sure.

New Yorkers seem more pleased with city services. 71 percent say they are very or somewhat satisfied with them. 27 percent say they are not so satisfied or not satisfied at all.

As for Governor Andrew Cuomo, a majority of state voters give him a thumbs up. 55 percent say they approve of the job he's doing, 28 percent disapprove and 13 percent are not sure.

Our poll found that New Yorkers are worried about the possibility of a terrorist attack in our state. 66 percent say they are either very worried or somewhat worried. 31 percent say they are not too worried or not worried at all.

But there is more division when New Yorkers are asked whether they approve of police focusing on Muslims to prevent terrorist attacks. 45 percent say they approve of the approach. 43 percent disapprove.

As for the mayor, his poll numbers may be a temporary setback, or perhaps a sign that New Yorkers have little appetite for a scandal at City Hall.
