Jesse Jackson? That guy's still around? I'd have thought he'd have suffocated as a result of being stuck up his own *** by now. I suppose he's got a respiratory bypass system or something....
Anyway, the question of pardon isn't all that clear. They spent several years going after her in congress, through law enforcement, in the media. The FBI cleared Clinton, then re-opened its investigation in a bid to sway the election, then cleared her again - but too late. It seems obvious that if she is now charged, it will be purely motivated by Trump's desire for political revenge (and his supporters' desire for jailing their political enemies). If anything seems to merit pardon, it's this kind of persecutory atmosphere.
Of course, the people calling for her to be jailed are just going to flip that statement on its head and claim that the fact that she hasn't been jailed is because of political favoritism. This claim will be made without the slightest shred of evidence that there is in fact such a conspiracy, the only thing behind their claim being the speaker's pre-existing hatred of Hillary and therefore, their personal opinion that she must be guilty.
(By "no evidence", I mean for example that nobody has ever disproved the FBI's claim that it had never recommended charges in Hillary's circumstances, only having recommended them in cases with additional aggravating factors. Disproving that would be evidence of favoritism. But nobody disproved it. They just chose to ignore the need to have evidence).
(Nevermind that the very same people calling for Hillary to go to jail have no problem with myriad accusations of fraud and sexual assault against their guy. That alone should be enough cause to ignore anyone jeering at the possibility of pardoning her.)
If someone goes to jail simply because of whom becomes President at a later date, then we really might as well call it quits.
