Hillary has mentioned that she will more than likely pick a female VP and Warren would be the natural pick and yes, she would attract the Sanders supporters. It would be a very strong ticket, but I'm not so sure Warren would accept ... she has stated in the past that she wasn't interested. Regardless, I think Cruz and Fiorina would defeat them. I have no doubt. As for Bernie ... unless Hillary is indicted and forced to step down, he's done.
