Sanders has refused to say whether he'll support her, has refused to raise money for state parties and has ran on the basis of 'Hillary is corrupt'
Thank you. That's because Bernie is all about himself, his ideology and this nonexistent "revolution" he's hoping for. He has no loyalty to the Democratic Party because he thinks it's owned by the boogeymen he so frequently demonizes: Wall Street. And yes, it's high time she went after him and give him a dose of his own medicine. Whoever is advising her to "play nice" for fear of "alienating" the Sandernistas needs to be let go from the campaign.
And to be precise, jfern, there is no "party unity" with the campaign allegedly going rogue since your candidate isn't even technically a member of the Democratic Party. Nice try again with your Sandernista propaganda, though.
