This statement says it:  "The will of the party is clear: More Democrats prefer Clinton over Sanders as their nominee." That would be "more Democrats" not more Democrats and Independents. If Bernie turns to support Clinton without expecting concessions, he breaks the trust that was his campaign and his followers are released from any allegiance. The success of a 74 year-old socialist Jew against the possible first woman President, former First Lady, two -term Senator, and former Sec. of State must mean something.   It's about the issues. 
Trump may become President because the system is flawed. It picks flawed candidates. It's a club run nomination process, not Democracy.
Clinton won't release her speeches. Trump won't release his taxes. Where is the difference?
Clinton accepted millions in corporate donations. Trump did not need to. 
Clinton has told a series of half-truths which is what we used to call lying. 
I won't be voting for Clinton. I will be voting against Trump.
