Like most you don’t seem to be aware of the other prong of the FBI investigation which is bribery, racketeering, money laundering and tax evasion.
I'm aware of it, they dovetail with the private server. And the possibility (probability IMO) that secret intel was used as collateral for these millions of "donations". But I really don't see how those crimes change the way this is going to play out.
Unless the FBI leaks a lot of very damaging and VERY SIMPLE info (Dem voters are effin stupid) she will still get the nomination.
