Her goal all along.
The presidency by hook or by crook.
Dear God, PLEASE take her out of the picture by whatever means You see fit and PLEASE do not let this election be stolen.
There is no scenario whereby Nancy Pelosi becomes President, Acting or otherwise.
If the choice of a President falls to the House (unlikely) and they tie (possible), the Senate will elect a Vice President who will act as President until the House is forced to choose.
One of the keys not discussed yet to the House electing the President is the fact that they are supposed to choose from the top THREE electoral vote getters.
Between November 3 and December 12, only ONE ELECTOR voting for someone othre than Biden or Trump could actually be putting up the next President.
