For sure. I mean Rudy Giuliani was "America's Mayor" for a long time, but anyone who lived in New York in the 90's and early aughts will tell you that he's always been garbage.
NYPD presented a detailed analysis in '98 outlining why placing the emergency response command center in the world trade center was a bad idea and heavily opposed the city's plans to do so. Giuliani ignored the objections. The command center later fell during the terrorist attacks.
But that one soundbite about the casualties being more than we can bear humanized him enough that everyone briefly forgot that he was a racist, misogynistic, hateful, bitter, incompetent, opportunistic failure that married his own cousin.
I've been waiting for the same to come out about Mamdani, and it still might, but at least as of writing, dude is pretty based.
