Is an interesting case in fact. In my opinion USA democracy is clearly into a transitional phase to became a monarchy. I would not bet money against Donald I becaming the first King of America. All ingredients are yet over the table.

1) Cult to the leader, Image printed on coins, posters, everywhere on TV and media. Fanatism

2) Religion serves the King. Divine intervention to justify power take. "God choose me in a divine mission to fix this mess" is a central part of the speech in every new monarch crowning. Trump is yet talking about that.

3) Exceptionalism and isolationalism, we are the best country and is cold and rainy out of my frontiers. Frontiers are very important for Kings as symbolic element of protection.

4) Extravagant behavior. Trump did all sort of outrageous things that would put anybody else in the jail, but got unscathed all the time. All kings do this. This is made to reinforce the idea of a special "superhuman" status.

4) Laws. This special status imply also that the law does not apply to the King and people will be carefully taught about that.

5) Killing competitors to the crown ("Hang Mike Pence" was metaphorical, but also works in a symbolic plane).

6) Wicht hunt behavior. As the King can't do wrong, scapegoats are required, normally on minorities.

7) Useful idiots. Extensive use of expendable pawns that are promised to enter the court, became famous, gain influence etc if they do a favor for the King. Those promises will never deliver.

8) Sucession. I would bet that the next elections will not have Trump as a frontman but a son of Trump will be the sure and only candidate. Every step will be taken to assure that not other has an opportunity inside the party. There will be a strong temptation and a lot of space to cheat in elections also.

9) And a component that is not still here, but I expect to see in the future is to disarm people that could pose a treat, weapon control but only for a part of the population. All Kings do this.
