Maybe I'm just really hung up on the dog thing, but that is the crux of it. There's basically no one who hears a story of shooting a dog for misbehaving and thinks, "yeah, that'll show the libs". That's not a story out of a politician's biography as much as it is a story out of a book profiling a serial killer's childhood.
71% of American households have pets [0] and there's a good chance that those who don't have had at least one in the past. There was absolutely no benefit to including that in the book, and I'd be stunned if the publisher didn't at least try to talk her out of putting it in there, given her political ambitions. If they didn't try to get it cut, they didn't do their jobs; if she ignored them, then she really does display a tendency to take pride in behavior that is recognized across the political spectrum in American society as cruel and antisocial.
She genuinely gives me the creeps.
