So one of the last things Trump did was pardon a whole shitton of scumbags.

But not himself, because you can't do that.

Anyway, putting his self-serving pardons aside, I have a serious question about how pardons work. Theoretically, could an incoming president say "Look, we all know that the War on Drugs is both racist and bullshit, and also racist bullshit" and then grant a blanket pardon to everybody convicted of possession? Or would this president have to issue all the pardons individually?
