I hope the Trump Team has plans to run against whomever the Dems replace FJB with, Because its COMING!
I do suspect that this is the case, and that it's been in the works for years. (My guess.)
BTW, (and hypothetically, of course) would it not be easy for Joe to promise to not pardon felon son if Joe knew that he's agreed to a graceful exit from the oval office, and that the Dem-selected replacement will take care of the pardon thingie? (Again, just my guess, the Dems and I don't correspond.)
