For John, BLUF: This is a nagging problem and even if Bernie Sanders is holding fire, it is not going away. Nothing to see here; just move along.
I found this on Facebook, posted by a friend of mine out in Kansas, a Bernie Sanders supportive—"Hillary Clinton’s Backers Want Obama to Grant a Preemptive Pardon—To Prevent Her From Facing 'A Martha Stewart Problem'". I don't know Orb Magazine, but the article seems plausible.
Remember when President Bill Clinton got in trouble over some creative explaining of his relationship with Ms Paula Jones? He paid a fine and found his law license lifted for five years.
I would be satisfied if the Attorney General was able to talk Former Secretary Clinton Hillary Clinton into, in exchange for a 30 day suspended sentence or a small (≈$10,000) fine, pleading guilty to a misdemeanor misuse of Government paperwork. Make it all go away and then let's get on with the election.♠
Of course we do have the current President saying that then Secretary of State Hillary Clinton did no wrong.
To close this out, it would appear that perhaps the main thing standing in the way of Ms Clinton making this thing go away is her Ego. The other possibility is that she lacks the confidence of her husband to believe she can step up, fess up and have the People love her.

♠ Yes, this means I do think Ms Clinton is guilty of not properly preserving government records, of recklessly endangering government secrets, of compromising classified information.
