That sort of transparent ploy isn't going to fly. For one, why would Joe Biden agree to put his head in the noose to do that?

The point is that no president can pardon himself so when the game is over the last "pardoner" is going to be left holding the bag.

I know it's a very unlikely scenario...but Joe isn't the sharpest knife in the drawer.

There is an understood rule that Presidents don't go after ex-Presidents in a legal way. Even Obama didn't try to prosecute Bush or Cheney even though the MSM and the DNC would have cheered such efforts. Whether Trump would feel constrained to follow that convention is unclear.
