Could you explain the position of Archduke-Elector? You've noted that your comment is sarcasm. And this gives me further pause as to the extent of Socialism's infiltration of the Catholic Church, and how we can stop it.
There was a time when European princes claimed the right to veto the election of any cardinal to which they were opposed. This right, dubious at best, was asserted only a few times in history.
Due to the sealed nature of conclave a cardinal representative of say the archduke of Austria would go in with a short list of unacceptable papabiles. In the event one of them was elected that cardinal representative would announce the royal or imperial prerogative.
