Let's say hypothetically that the following events happen:
Hillary Clinton becomes the Democratic nominee for President of the United States in 2016.
Hillary chooses her husband Bill Clinton to be her running mate.
Hillary wins the 2016 election and becomes President, and Bill Clinton becomes Vice President.
Sometime during her presidency, Hillary becomes incapacitated and can no longer serve as President.
What would happen in this scenario? Would Vice President Bill Clinton become President since he is next in line in the presidential line of succession? Or would he be ineligible to become President since the 22nd Amendment bars a person from serving more than two terms as President?
Or would he not even be eligible to become Vice President?
