[assuming they're actually popes, just for the sake of argument] ... if Bergoglio resigns, the Bennyvacantists would have to hold that the subsequent election is still impeded by the fact that Ratzinger is still the pope. And would the Bennyvacantists hold that the Cardinals appointed by Bergoglio are invalid and could possibly invalidate a fair number of future conclaves. I believe Bergoglio has selected about 2/3 of the voting-eligible cadinals.
