Well, to answer the question, "Who's next?", I'd have to point out that the Pontiff has a feeding tube stuck down his throat, and that he can't talk. And I'm sure that his reflexes aren't what they used to be.
So it looks like all that's needed is a less-than-reliable witness to step forward and testify that "he really never wanted to live that way" . . .
Lucky for the Pope, he doesn't live in America, I guess.
Yes. Good news all around. The pope can be helped nutritionally and he can stay away from the USA.
