Without being a monarchy...
I'm not looking for an American King, just a *presidency that resembles more of an elected monarchy in a traditional or decorative sense. Like John Adam's dream of "His Elected Majesty" but embraced fully by Washington.
Maybe a brief trip to Europe after the Seven Year's War as a hero gives Washington a good look at crown jewels, thrones, banquet halls, etc. Pomp.
At the very least, could there be a crown of some kind and a royal-esque uniform that evolves over the years?
It doesn't necessarily have to butterfly a lot of presidencies, either. I can't see butterflies developing from nicer clothes and titles being Mothra sized, at least for some time...
Anyway what do you guys think?
