Elisabeth Kübler-Ross gained some minor fame as a psychologist for studying the stages of grief.  She noted five major stages: denial, anger, bargaining, depression, and acceptance.   In watching the Democratic Primary (which ended roughly the moment NY polls closed), we have now moved well into the second stage of the model.

Anger:

In Nevada, however, that first day of voting was only the beginning. In an intermediary round of county caucuses, the Sanders campaign turned out greater numbers, which tilted the balance toward his side. At the state convention on Saturday, Mrs Clinton once again had the higher turnout – in part because some Sanders delegates showed up late, provided insufficient information or were not registered as members of the Democratic Party.

The Sanders team wanted the rules changed to accommodate their delegates. The Clinton team refused. Then all hell broke loose.

Anger is the second stage in the grief model.  A great many people were passionately attached to the Bernie Sanders campaign, and watching something you love die is never easy.

Next up is the bargaining stage that will come after Clinton seals it up *officially* in NJ.  The idea here being that Sanders will get to have/be bribed with more power in the Democratic party in exchange for not tearing it apart (he has bee a Democrat for about a year now).

Depression will set in during July when a lifelong independent fails to get permission to re-write the Democratic Party platform (especially considering the actual nominee is a hardcore policy wonk).

Acceptance comes in August with the convention, and the *start* of the mainstream campaign against Voldemort and the United States’ racist and bigoted past.
