If Trump is popular in 2028, then Trump will run. He will find a way, and I hope he is healthy enough to do so.
No president who has served TWO terms, sand part of one being president due to the death of the president, when he or she was the VEEP, is allowed to RUN for a third term!
And on top of the law, Trump will be in his early 80s, in 2028 and deserves to go back to private life after having gallantly served as president for TWO FULL terms, after having been cheated out of his consecutive one.
