538 had a pretty good chat on it. I think this was a pretty good quote:
"A lot of the criticism of the book goes something like “Clinton is blaming everyone else for her losing” instead of taking responsibility.[...] That criticism is such a dumb argument that it’s not really worth debating it."
I agree so I won't. The Bernie Bros* were never all that bright so trying to reason with them isn't worth the time.
