There is no “we was fooled/robbed so we get a do-over” provision.
Biden is the legitimate VPOTUS according to the Constitution and would serve if, for any reason, 0bama is unable to serve.
Both Article II and the 25th Amendment agree that Biden would be President if, for any reason, 0bama was unable to serve as President.
I see so you are claiming that such is written then such is Iron Clad and no ambiguity exists. Correct?
BTW if you read your statement above verbatim the exact opposite is True.
