Shuffles by one if it has to, but anyone with a boss can just be replaced because that higher authority exists.
Usually this is discussed with just the president, who has no higher authority, or in the case of mass death like nuclear war, with an assumption that we lose a good chunk of the government. But not this conversation, where VP matters more than P for certification.
That was Illinois but honestly it’s just obvious in any state with a recreational/medicinal use law.
It’s ridiculous they’re allowed to keep using it as an excuse in general.
