Why Attack the Berniecrats now?
Obviously Hillary is not interested in playing patty-cake for the sake of party unity in the Age of Trump. Screw that. She has accounts to settle.
Surely she and her confidents knew that these passages would anger Bernie’s followers. It would make us even less likely to want anything to do with a political party controlled by her wing. And that I believe is her point. She wants to purge the trouble-makers. She longs for the days when she and Bill could dine with Alan Greenspan and the super rich, and no one noticed or cared. But the financial crash, Occupy Wall Street, Elizabeth Warren and then Bernie and his passionate followers put enormous pressure on the cozy relations between Democratic officials and financial elites.
As Hillary makes clear, it is much easier to attack the radical reformers than to institute radical reforms.
