No, you are not laying this at the feet of Die Hard Bernie supporters. We are not the ones who are splitting the party.
Hillary Clinton, the corporate media and the party elite are splitting this party up by forcing Hillary down our throats.
She was the anointed candidate only because no one would run against her, till Bernie stood up. Then the DNC and corporate media did everything they could to contain him but in spite of all that he has come this far.
Hillary has won states she should have and won the ones should should have handily but this is far from over and Bernie's states are still to come and lets not forget he has the money to be competitive in the ones he needs to win.
This is going to the convention where anything can happen.
