Nah, I don't waste brain cells remembering the faces of the many politicians.  Yes, the mainstream media is pretty much a homogeneous mass and this artist dude managed to get his photo published in the media which was likely his choice and the media's choice for disseminating it.  Other folks and at other times would have considered the photo to be partisan and in poor taste as it demeans without substance.  Kinda like publishing a photo of somebody picking their nose.
