Is there really any possibility -- or any real cause -- for indictment? After reading your question I did a web search and none of the cries for indictment appeared to be coming from unbiased, reputable sources.
The latest phase of this saga was broken on Tuesday, January 19 by Fox News. part of the Murdoch media conglomerate it's hardly the most reliable source, though, of course, it may be accurate. (Even Murdoch will use the truth if it suits him.)
Personally, I think Hilary was a bad choice for the Democrats and would rate her little chance of winning. Fortunately for them, the GOP seems intent on self-destructing by rallying behind Donald Trump. He's the best friend Hilary has.
Just for the moment the chance of indictment seems more of a beat-up than a realistic expectation. Sure, she was sloppy when she was S.of S, and sure, she lied about it., Fancy that. A politician who tells lies. Whatever next?
