Any sane person's interpretation of the Constitution is that he cannot be president again. he might be able to run, but to what point? he is too diminished to be elected, and cannot be president again... But with the 20% that will support him no matter what, he may well be able to get the party of trump nomination.He cannot run again. Besides he is too diminished to try. He wants to, so he can stay out of jail.
Sometimes trump just is trump, and does not care about the destruction he does along the way.
