I never understood "because shes a woman", especially pointed towards people that are more liberal/progressive. I for one would have rather had Warren over Sanders, but he ran so I went with him. Sure there are dumb republican guys out there but using it against people that basically believe your side is counter productive and leads to in-fighting.
As far as Hillary goes, I think she is unnecessarily secretive about everything. Relies to much on her staff to do the politicking/message control.
But in the end, Hillary is more Sanders like, at least in what she is proposing now, than when she started the primaries. I'm no Bernie or Bust person, People say he "sold out" some how for endorsing her, but she really did move towards and embraced him, almost more than any other primary winner.
