I didn't see/read the interview so cannot comment specifically on that.. and I have no axe to grind either way with Hilary but what I will say is that I personally have never, but never, seen her behave with anything other than dignity. I very much doubt, therefore, that she is over-analysing anything.
I'm wondering if Bernie is doing the same thing after his failed attempt at 1600 Pennsylvania Avenue? That's probably why he puts a scowl on his face every time Hil-LIAR-y's name is mentioned around him.
