The Democrat Establishment is in desperate straits - damned if they try to suppress Bernie Sanders, and damned if they don’t. The situation has progressed too far to be easily reversed, without losing huge boatloads of Democrat partisans on one side or the other. There is no possible coalition ticket between the Democrat Socialists and the more moderate Democrats that will satisfy any significant number of unaligned moderate voters they must attract to gain even a close plurality to the Republicans in most venues, as there will be a couple of splinter parties springing up that will take advantage of these schisms in the Democrat party itself.
It could still happen, that Bernie or someone of similar convictions could gain enough advantage to eke out an Electoral College majority, but they have put a huge handicap upon themselves.

totally ...we could call that situation “The Bernie Problem” or say that the Democrats “have a Bernie Problem” ...
