So, am I understanding correctly that, similar to his shitty piecemeal Murican Flag backdrop showing he's a true patriot, Johnny deleted this because he thinks his potential voters in district 8 are likely racist, and just like his faux Red Sox-ism, he's trying to play the part?
I mean, there's literally no other reason to delete this tweet; it's totally "safe" from the perspective of his usual milieu and the SJW types: whites bad, poor blacks, etc. (I actualy think it's kinda hysterical that Sony intentionally (accidentally?) pissed in peoples eyes with this "White Aryan Amazon PSP" ad, but that's another story!)
Wu is revealing just how patronising and condescending he is by how he's trying to "play the game" to finesse the votes.
