If they let it go, it is a horrible precedent. But, again, we are talking about the Dems here. Conventional rules don’t apply. And the Clinton “magic” is not what it used to be.
I suspect Bill knows what is going on too, which is perhaps why he’s been so subdued lately.
You can say many bad things about Bill Clinton — and, Lord knows, I have! — but he is one shrewd s.o.b. I suspect last year's photo of Obama and Bill Clinton playing golf, with Clinton looking upset, was exactly what it seemed: Clinton imploring Obama to get the FBI et al to lay off Hillary.
Yes, Bill Clinton does seem subdued. Do freepers notice something else? The Dems are very, very quiet about HRC’s email scandal. For example, You don't hear obnoxious Nancy Pelosi defending HRC; you don't really hear any Dems defending HRC.
The investigation probably covers Bill’s criminal actions too. I think they may be holding off so the indictment comes when there is a new president that won’t pardon her.
