You're talking about a pardon from Biden? In this universe?
I mean you do realize he put $69 million into the midterms for Democrats right? Pardons have been had for far less from much more notorious people.
Pardoning him would be very costly. I cannot imagine Biden doing it.
It's not even necessary steay unless there is a prosecution.
If it's years before a conviction [1], who knows who will be president. But all presidents have given controversial pardons... some with a very strong quid-pro-quo smell (Clinton and Mark Rich).
