Meh. The book (1900, or The Last President) is about William Jennings Bryan. (I Just read the first chapter+)
Populist wins and takes down the current elite. It's a common story. The only thing making it interesting is he chose the name "Baron Trump" for his earlier stories.
Life is full of weird coincidences. It's either that or that the Trump family is long pre-destined for this time and had heralds prophesying their reign. ALL HAIL TRUMP!
