Here's one way to look at the problem:
The College of Cardinals is both nominating committee and electorate. The only way to become a Cardinal is to be appointed by the Pope. So when any pope knows he's coming to the end of his run, he can plan ahead to get his chosen successor elected merely by appointing Cardinals who will vote his way.
Given that the last Pope is still alive, even though this outcome is tragic it was not unexpected: not many Cardinals are going to support someone who is likely to change course when their last boss is still around. In fact in hindsight, that may be the very reason the last one resigned while still alive: to guarantee that his successor would be just as much a Rat as himself.
So call him Pope Rat II.
BTW, with his positions, his choice of name is an insult to St. Francis of Assisi -- but I presume that's not the Francis he had in mind anyway.
