If you are trying to come up with Forever Name for Trump good luck.
If 'Literally Hitler' didn't work to keep him out of office, probably nothing else will stick.
If you started the 2016 campaign with something more reasonable, like 'Shady Donald', or 'Mafia Don' it might have stuck. But when you go full Hitler at the beginning, and he doesn't come across has Hitler, you've lost all naming credibility.
How does your theory pan out with all the other candidates who were compared to hitler?
