I wonder if it might be useful to refer to him as Trump the Inferior, and to his appointees/departments

with the same adjective.

The Inferior Defense Secretary.

The Inferior Department of Justice.

The Inferior administration.

It's very important to Trump that he be viewed as "the greatest." In his own poor excuse for a mind, he's Trump the Great. Greatest president. Greatest real estate developer.

Which of course he never was and never will be.

I have seen others refer to him as Trump the Inferior, but it wouldn't hurt to do so more often, to trigger his inferiority complex in a way some other nicknames and descriptions won't.

If you call him a mad king, he hears the word king and tells himself the insult shows even his enemies see him as regal.

Call him Mango Mussolini, and he hears the comparison to Mussolini as a compliment.

But call him Trump the Inferior, with his Inferior administration and Inferior Cabinet...
