Ladies and gentlemen, our scandal du jour is Foleygate, not Predatorgate. In order for the "-gate" suffix to properly identify a scandal that will transcend partisan and ideological interest, without first glazing over the eyes of those who aren't politically-obsessed, it has to start with a banality(eg., Water-gate, Monica-gate, Contra-gate, etc.) When you start it with a loaded term, you run the risk of killing the outrage, as liberals did when they began calling the Plame Leak controversy, "Traitorgate". If the word that precedes "-gate" is inherently criminal, there's no point in using the suffix in the first place.

UPDATE: Some particularly sloppy usage, here. "Spitgate"? Donnez moi une break !!
