It’s hard to know a vacuum.
I don’t see how Hemmingway can call Romney an “otherwise exemplary man” after setting out what he knows about him and the lies in the book, but the final paragraph in the article is this:
“By contrast, until I read Romney: A Reckoning, it had never occurred to me that the most obvious reason Romney’s political career petered out in a hail of grievances is that he’s turned into — and it pains me to say this about an otherwise exemplary man — kind of an asshole.”
