Monster vs Ken Starr

Ok, I give up. Which is which?

Samantha Power says Hillary Clinton is a monster. This, after one of Hillary Clinton’s people compared Barak Obama to Ken Starr.

So far, it’s all good and wholesome mudslinging. But then (according to this AP article), Clinton said the two cases are different, because “one is an ad hominem attack and one is a historical reference.”

So which one is which?

I’m afraid the distinction escapes me.

I do notice that one of Barak Obama’s unofficial advisors resigned, while Sandy Berger is still an unofficial advisor to Hillary. I don’t understand that distinction, either.
