Capt McQuigg: Why? Also, we are presuming the sede position for this consideration, which it does not look like you also do. For the sake of argument, do you think that a conclave would be the solution if there was a vacancy of the Holy See? This was the normal solution to all previous vacancies. I think that things like sedeprivationism and other ideas are false solutions to divert Catholics from the normal solution of a conclave.
Even presuming PM's conclave was valid, given the confusion today, I thought maybe a new run-off election could promote unity and certainty.
Food for thought, maybe related:
""There are two instances in which the cardinals may call a council without permission of the Pope. The first is when it is doubtful as to who the rightful Pope should be; and the second, when the Pope should notoriously lapse into heresy. In the first instance, we are guided by the principle 'a doubtful pope is no pope'; in the second, the council will be called to declare what is already an established fact, for the manifestly heretical pope deprives himself of office without needing the decision of the Church." -- St. Alphonsus Ligouri"

http://www.dailycatholic.org/issue/05Oct/oct13tra.htmWherefore, if the Universal Church ever secedes from a Pon- tiff, that very fact constitutes an infallible sign, according to what had been stated earlier, not that he who had once been Pope has now been deprived of his power by virtue of that defection, but that he had never been a true and legitimate Pontiff, since Christ, faithful in his promises, would not be able to permit that the entire Church adhere to a false Pontiff or reject a true one.

http://www.catholicapologetics.info/modernproblems/currenterrors/sifting.htmOne problem with this last quote is that no real time frame is given, so if everyone started recognizing PM as pope, in theory it seems this could "convalidate" him, even if his election was invalid, ceteris paribus (all else equal).
