On this particular subject, there’s a lot of obfuscation because most of the commonly cited opinions on this are from Leftists trying to demonstrate that Ford’s pardon of Nixon was somehow illegitimate. Reality, once again, is not on the side of the Left.
And in all of this, if there's child porn on Corlos Danger's/Huma's laptop, a pardon will be necessary for that as well. I think Obama will stay far away from pardons.
