I believe the intent of that is if there is no clear winner in the Electoral College and Congress is deadlocked on deciding a winner. Assuming Obama wins the election, then a president would have been chosen by the electoral college. If Obama is then found ineligible then I think it would be treated the same as if he had died, and Biden would become President.
Or if Biden isn’t the VP at that point...we get Hildebeast.
Yes, if he assume the office of the presidency, but that is NOT the case here IF he is deemed a total fraud of eligible to assume the position. Biden is NOT qualified either???
