This week Joe Lhota warned us that under Bill de Blasio, New York will probably be run by violent biker gangs and every square inch will be covered in graffiti. (Damn you, Banksy!!) The frontrunner responded Thursday with an upbeat ad featuring his 18-year-old daughter Chiara and her signature flower crown (it’s not the one she wore on primary night, so apparently she owns several). It doesn’t really recapture the magic of de Blasio’s previous ads, but the conclusion says, Hey, remember that Dante ad? That was a good ad!
