Aiding and abetting potentially indicted people [View all]
All of the Clinton supporters who are worried about Sanders continuing his campaign should be more worried that he won't be around if and when Bill and/or Hillary Clinton are charged with criminal charges as a result of decisions being made relative to when and how speeches were paid for and/or when and how contributions were made to the Clinton Foundation. Here is one of several apparent situations of interest.

Therefore, they should be worried about are these supporters giving aid and comfort to potential criminals. Will they have as part of their resume that they gave aid and comfort to potential criminals? That is much more potentially serious than being worried about Sanders quitting the "race" sooner so the "supporters" don't have to worry about negative comments. If they can't handle negative judgments during a primary, how are they going to handle it during the general election where Trump is already calling Clinton "crooked Hillary"?
