I really love Warren for handling these types of attacks. For starters, it allows a Presidential candidate like Sanders or Clinton to remain
Presidential, which is something that Donald Trump only believes he can do because he is an egomaniacal asshole that claims an ability to do anything and everything better than anyone who has ever lived. Additionally, she is largely a target that has so far escaped any significant negative branding. Donald Trump has responded to Warren's attacks by calling her "goofy" and by trying to re-hash a 2012 controversy related to her alleged native American history. I don't see either having the same type of punch as the ones that Warren continues to lob against Donald, like these gems:

Is it possible that Warren's combination of providing unity within the democratic party and her ability to act as an attack dog during the campaign could lead us to have an all-female democratic ticket?
She is certainly making that argument hard to ignore.
