Clinton supporters (including myself), Hillary is not doing herself any favors with this talk. It's opening up deep wounds that were just starting to heal. Like it or not, Bernie commands a huge wing of progressive politics which includes a lot of millenials, regardless of the practicality of his ideas. Hillary should not poke any more nests and make people who reluctantly voted for her regret it. It's time to heal the party and if she wants to play a major role, she should align herself with Bernie wing instead of looking inwards and being defensive. And waiting another year or two for the book would have helped.
Bernie supporters, you need to realize the amount of vitriol die hard Berners and BoBers directed at Hillary during the primaries. She isn't wrong, and what she is talking about is not unprecedented. Look up PUMA's from 2008. BoBers continued to drag her all the way in general and there is also a good cross section of Bernie voters who voted for Trump. Lot of talk from these folks is still acidic and just unrelenting and many times unfair.
Both the flanks need to come together right now to fight the common enemy: Nazis.
