Terminology: Clinton Versus Hillary

It seems to me when this presidential campaign began, the customary reference was to "Hillary" or "Hillary Clinton" and usually a reference to "Clinton" meant her husband.  These days though I think I see a presumption that "Clinton" will refer to Hillary; that's the default these days.  Maybe it's like "mail"--it's almost like you should use "snail mail" if you mean USPS.
