Never liked him, but I acknowledge that he had some effective economic policies during his time as mayor. He was at least competent and sane. He went completely off the rails a long time ago, though.

He's often credited with cleaning up Times Square, which was known for prostitution back in the 80s. But honestly, he reaped what his predecessors sowed to a large degree.

He used 9/11 like his personal sword and shield. He was lucky to be in a prominent position related the biggest and least controversial issue in America. I don't imagine he ever would have been on the national stage otherwise. He was pretty much at the natural end of his career before then.

NYC has a history of conservative mayors, which seems a bit odd since we're so solidly liberal in federal elections. It sure doesn't help when we get a Democrat as infantile and corrupt as our current mayor, Eric Adams. See: https://en.wikipedia.org/wiki/Federal_prosecution_of_Eric_Adams
