All this is very interesting but probably no longer relevant. If Hillary wins she will stop the investigation and destroy all evidence. And Obama will probably pardon anyway. If Trump wins they will find a way to stop him from becoming President probably through paragraphs 1032 and 1033 in the NDAA. What happens after that is unknown other then maybe throwing to decision to the House to elect the new president which may pick Hillary even though she lost. Then Obama could pardon her and that would be that.
