So America returns to monarchy huh? If you are trying to make people's heads explode let's also assume that with advances in medical and cybernetic technology, Trump is able to extend his lifespan and our redheaded royal cyborg is able to lead for thousands of years ! :).
FDR got 12 years over 4 terms, a few minor changes to the law and we ought to be able to double that. Think of what the judiciary would look like after 20 years.
And it would keep a new generation Bush from betraying the Revolution like HW did to Reagan.
