I've been thinking about this all day, and if Trump dies and Vance takes over I think we're looking at something like regime collapse.
Vance has proven incompetent, the coalition is already fracturing, and his impulses are authoritarian. Very, very bad combination.
Notable detail in the NYT story is, besides Miller, Vance was the WH's most ardent backer of unleashing govt repression against Americans. Consistent w/ him endorsing* a book that literally calls for importing European & Latin American fascist tactics into the US.
