The idiotic fixation of the ticket of Obama/Biden does nothing to change the clear meaning of the Constitution.
25th came about because the intent of the founders was not clear on the matter of succession and Understand they wrote the matter of succession based on what they knew at the time. Now can you tell me what they "knew" about the Vice President position in their day that is not True now?
Joe Biden was elected VPOTUS of the USA by the electoral college. If for any reason the POTUS is deemed ineligible or unable to seve during the time Biden is VPOTUS, then Biden becomes POTUS.
That is the direct language of the Constitution both in its original drafting, and according to the 25th Amendment.
There is no “we was robbed so we get a do over” clause.
