I don’t think it matters. Obama will give Hillary a blanket pardon just before the door swings on his backside.
If he doesn’t Hillary would be seeing bars within the year. We’ll see just how strained Obama’s relations are with the Clintons.
I think that Hillary has problems whether she is pardoned or not. If she gets the pardon, it just plays right into Trump's anti-establishment campaign. He could point to the pardon as just another example of the government elites playing by a different set of rules. Of course, Hillary is toast if she is indicted by the Justice Department run by a Democrat administration.
The best thing that Hillary can hope for is that the Justice Department acts quickly and decides to exercise prosecutorial discretion and pass on bringing charges. However, she can't have this done in the middle of the general election campaign or it is the same situation as a pardon. However, it might already be too late for this action to keep this issue from undermining her campaign.
