NEW YORK (CBSNewYork/AP)New York City Mayor Bill de Blasio‘s approval rating has fallen over the last two months, a new poll says.

A Quinnipiac University poll released Tuesday says that 45 percent of New Yorkers approve of the job de Blasio is doing. Thirty-four percent disapprove.

The new poll has a margin of error of 2.8 percentage points.

De Blasio’s rating is down from Quinnipiac’s last poll, which was released Jan. 16 — a little more than two weeks after he took office. In that poll, 53 percent approved of the job he was doing, and only 13 percent did not.

“The charm, the great numbers that he showed at the very beginning, have understandably gone down a little bit,” Maurice Carroll, director of the Quinnipiac University Polling Institute, told WCBS 880’s Rich Lamb. “They’re not bad.”

The numbers are slightly better than a Marist College poll earlier this month that showed 39 percent of registered New York City voters believe the mayor is doing a “good” or “excellent” job.

De Blasio has weathered a series of missteps, from his handling of a pair of snowstorms to the call he made to the NYPD on behalf of a political ally to CBS 2’s Marcia Kramer catching his motorcade violating several traffic laws days after vowing to cut down on pedestrian deaths.

He has also been battling Albany for funding for his universal pre-kindergarten proposal.

White voters most strongly disapprove of the job de Blasio is doing (45 percent) while black voters (60 percent) overwhelmingly approve.
