UTC   Wikipedia is not a dictionary  Its true that as a purely semantic thing anyone who elects someone while breaking faith with someone else could be called a faithless elector or a traitorous voter or untrustworthy votecaster or any other synonym  But as a technical term faithless elector is used to refer to members of the United States electoral college who vote in certain ways  So we can have a Wikipedia article about faithless electors without discussing that hypothetically there might be some other country somewhere in the world that also uses this term      April
