I don't rule out Hillary winning in November but she has been badly tarnished by the email scandal and her latest health issues.
At this point, I think there is a serious possibility that Trump may win and that would be disastrous for the country. If she really cares about some of the issues she has been talking about, she would realize how badly damaged she is and let someone like Biden or Tim Kaine just be the standard bearer into the election.
The recently hacked emails of Colin Powell shows that he has been scathing about Trump but he has not had kind words for Hillary either.

When 70% of the country distrusts a candidate, it is difficult to recover and some of the credibility problems she has have been of her own making.
As Democrats, we need to ask ourselves whether Hillary is so badly damaged that she may end up helping elect Trump to the presidency.
