Menino didn't run again (he'll be teaching gov't or something at BU). The current mayor, Marty Walsh, is the one I suspect of being behind this -- at least, according to local news reports, he's been in the forefront of trying to get the gays into the parade (after almost 20 years since the SCOTUS decision). He has announced (as if anyone cared) that he will not march if the gays aren't allowed to. Menino never marched, and no one missed him -- he did march every year, though, in the Gay Pride paraded (though one year, there was one . . . float? exhibit? whatever that was so shocking he was apparently angry, but he didn't know about it until the parade was over.
Ah, the story of the very interesting life of the Menino boy.
IOW, "Shut-uppa you face ... play like-a dum, take-a da money."
... and the cannoli.
