I agree with Carl that the attacks on Hillary ARE NOT rational.
She has a pretty progressive record,ESPECIALLY compared to ANY Republican candidates. 
The fact that all too many "Bernie" supporters say they may NOT ONLY NOT vote for Hillary if she is the Democratic nominee, but may actually vote FOR THE REPUBLICAN  (Trump or Cruz) is BEYOND Appolling!!
The far left can be every bit as "mentally unbalanced" as the far right, unfortunately.
