Big Will needn't worry, the age of Trump won't be ending anytime soon.
This is the classic Octavian/Augustus M.O. Trump has to say, no, I don't want any additional power. At a later time, due to his overwhelming popularity, the people will demand it and it will happen.

Until then Octavian had been ruling the state with his powers as triumvir, even though the Triumvirate itself disappeared years earlier.

The Senate confirmed Octavian as princeps, the "first among equals", and gave him control over almost all Roman provinces for a tenure of ten years. This limitation was only superficial,
