Why does Hillary Clinton go by HRC, when her actual middle name is Diane?
Interesting. But why do people use initials as shorthand in the first place?
There could be many reasons. Some people might prefer the brevity of initials, while others might like the anonymity they provide. In the case of Hillary Clinton, her staff may have used HRC to avoid confusion with other people with similar names or titles.
