Is Bernie's party over?

This article shows how Bernie is different:

"There is a difference in kind between Bernie and the other Democratic candidates, a difference unlike the differences among them. It’s the difference between a principled Social Democratic program to meet human needs, based on and supported by a mass movement, and a program of neoliberal tinkering to protect profit-making possibilities, based on and supported by capitalist donors/the donor class."

The article also notes that the Dem Party itself will try anything and everything to prevent Bernie's nomination, which is the sad truth. But the author also notes that if that's the case, again, then it's the death of the Dem Party and Bernie and company will need to form a Third Party. Hopefully the Progressive Caucus will join that effort.
