Looking at it today, it appears to be clear that there is no, and there has been no semblance of, real "unification" in sight for the Democratic Party. Clinton and Sanders offered two totally conflicting political and economic perspectives - and it manifested in an astounding, generational line in the sand. Those who may have been first politicized from this most recent election have had a brush with a divisive, antiquated and corrupt system and since walked away with permanent scarring, for better or worse. With the established wing of the party repeatedly proving itself unwilling to come to terms with the rise of the further left, there will be no meaningful unity.
The damage of the primary has been done and there is no going back, so I certainly believe it makes sense to debate the direction of the Democratic Party with this defining primary in the background.
You make it sound so dramatic.
