Imam Obsmessiah pardoning Hildabeast won't wash, because he's in on the crime syndicate: Ordered heads of the injustice department and the FBI to both commit obstruction of justice by NOT inditing or prosecuting Hildabeast.
It would be like AL Cape pardoning Frank Nitty so that they both escape justice. However, since they are both involved in the RICO crimes, the "pardon" would be invalid and both would be prosecuted.
If Obomination is the least bit smart and wants to protect himself, the best course of action he could take would be to not pardon her.
Hildabeast and Billy the rapist have become a massive liability to Obomination's future artery the White Hut. You know what happens within the mob when one of its members becomes a "liability"... just ask Jimmy Hoffa, or Bugsey Seagle.
Elliot Ness is on the scene now and OBuggery is on the hot seat privately a lot more than most folks know.
