If you want to read a book describing what it would be like post Trump, may I suggest the one I’ve just finished? Called Warday by Whitley Streiber and James Kunetka. Oral history story of 2 journalists who tour America 5 years after a limited 36 minute nuclear strike. Really prescient.and disturbing.
Strieber is the loon who wrote Communion about alien aductions, but Warday is excellent.
