Trump is a clone of Grand Pa Freddy, whose life attitudes and behavior were detailed by the Britannica;
the portrait of someone lacking both Character and Honor who fled Bavaria to avoid a firing squad.
Yet these types are able to sway the impressionable to pledge their unquestioned loyalty.
History details many of these kind; most notably Benito Mussolini, in our era.
Sadly it always ends poorly, in tears and far worse.
