If they want Bernie out this could go one of two ways.
#1 is that they take advantage of his fondness for Dachas in the countryside in the manner of the Soviet leaders he wishes to emulate, and Bloomberg cuts him a big friggin’ check to go away.
#2 is that he’s so captivated with his potential place in history as having played a key role in turning the USA socialist that when they screw him over at the convention he stages a third-party run and takes all of his supporters with him. At 78 he has little to lose, and when Bloomberg comes in a distant 3rd. the socialists will have effectively won their battle over the moderates within the Dem Party.
Hard to read where his head is right now.
#2: Dilute Bernie as much as possible and force a brokered convention? They would be smarter to get behind Bernie and "go for it". That is what I expect will happen after Super Tuesday.
