This is unprecedented , but it seems to me that if the presidential candidate turns out to be ineligible, then the VP on that ticket cannot be said to have been legally and validly elected either. The whole ticket (Pres and VP) is ineligible . Biden cannot be sworn in as president.
So in this scenario, it would appear that the third in line...the person who really and indisputably elected to public office..is the actual president of the United States of America. That would be Nancy Pelosi.
I'm not sure we aren't better off with malignant narcissist BHO and the dimwitted plagiarist and character assassin/fantasist Biden. :-(
I would want to have someone who is Constitutionally eligible sitting in the chair.
This could be why perhaps there is so much cover up...perhaps by more individuals than Bo and his thugs. Pelosi would be a nightmare on wheels!! Frightening to imagine!! Oh the thought even!!
