What would be really hilarious is, I think that would allow her to serve two more 4 year terms after her 2025-2029 term ends because she would not have run as President the first time.
That’s incorrect. The 22nd amendment states: “no person who has held the office of President, or acted as President, for more than two years of a term to which some other person was elected President shall be elected to the office of the President more than once”. So unless Biden would wait for at least two years before stepping down, Harris could only be elected for one more term.
