There is a difference in the nature of the attacks.
Bernie supporters have legitimate reasons for mistrusting Hillary. (Mainly ties to Wall Street, corruption, foreign policy, etc)
Hillary supporters just use politics. Unelectable, socialist, extreme, his supporters are racist, etc. They are even jumping on this quote. She's a good debater. It's just politics. There is no discussion of policy.
As an undecided voter (independent so can't vote in the primary), Hillary does some some positions that could be better than Bernie. Gun control and maybe education.
The debate is definitely uneven. I wish Hillary supporters backed her on policy. Support for her is justified by attacking sanders, not her policy.
