New York City’s best mayor of the last half-century? A new poll says city voters rank Rudy Giuliani tops.

A Quinnipiac University poll released Thursday found 31 percent of city voters said Giuliani did the best job. That compares to 25 percent for Ed Koch and 24 percent for incumbent Michael Bloomberg.

David Dinkins and John Lindsay got 6 percent each. One percent chose Abe Beame.

A Giuliani spokeswoman didn’t immediately return a call. Giuliani served from 1993 to 2001. He was widely praised for his leadership after the Sept. 11 terror attacks.

The poll shows 53 percent of voters approve of how Bloomberg is doing the job now. Forty percent disapprove.

The poll surveyed 1,017 city voters. Its margin of error is about 3 percentage points.
