It really can happen here
I remember reading Sinclair Lewis' "It Can't Happen Here" in college and it has been much on my mind with the rise of the Trumpenstein. This article from Salon.com is an excellent piece IMO, contrasting the real Trump with the fictional Windrip of the novel.
With his careful mix of plainspoken honesty and reactionary delusion, Trump is following an old rhetorical playbook, one defined and employed successfully in the 1936 presidential campaign of Senator Berzelius Buzz Windrip. In his campaigns promotional book Zero Hour, Windrip laid out the classic nativist call to action that Trump would pick up nearly word-for-word:
My one ambition is to get all Americans to realize that they are, and must continue to be, the greatest Race on the face of this old Earth, and second, to realize that whatever apparent differences there may be among us, in wealth, knowledge, skill, ancestry or strengththough, of course, all this does not apply to people who are racially different from uswe are all brothers, bound together in the great and wonderful bond of National Unity, for which we should all be very glad.
