I see this as being a very frustrating election cycle for Democrats.
The MoveOn.org folks have been hoping to have street riots when Occupy Where-ever was started. They came close to having a summer of riots in Ferguson and Baltimore with Black Lives Matters, but didn't quite do it.
There is a radical part of the Democratic party that really wants blood in the streets and thinks it will help elect Democrats. I see them getting their wish for blood in the street this summer, but not in electing Democrats.
(Just to make sure that there is no confusion, is see the blood as being that of demonstrators and police. There were far too many police ambushes set this last summer for it to have been by accident. These Democrats want to foment domestic terrorism and they are likely to spill any blood they can.)
Now back to Hillary. She will either be indicted, drop out for medical reasons, or move to the shadows and let some proxy campaign for her. That proxy can't be Bill Clinton as he also is in frail health and the way he has been scolding hecklers shows he is not up for a hard campaign.
At best the Demo's will need a strong VP candidate to do the campaigning while Hillary recuperates and rests. The problem is that Hillary will not allow anyone to upstage her, so she will not pick a strong VP. She wants two full terms as President as she has a lot of money to make from the office.
This is mind boggling - she's already got more money than she can spend. Why keep trying for more?
