She only changed her stance because of pressure from Sanders. Given her "private and public policies", I didn't believe her.

She was against it, after she was for it. No one believed her, especially since Terry McAuliffe let the cat out of the bag.

[EDIT:] I'm surprised the DNC downvoted this, since McAuliffe is yet another plausible person to blame while diverting attention from their terrible and misguided primary-fixing.
