Too late.
Too late for even a brokered dem convention.
Only if Hillary steps down which she will not do.
cough cough plop plop...
She will step down when threatened with an orange jumpsuit for fear that her thighs will show more prominently.
I believe she will step down for “reasons of health” or maybe she will get sick and drop out. That or Assassination is possible—I wish no one ill but, I believe that the Democrat Party will do anything—to keep in power. Biden/Warren ticket might work—that or a Kerry/Brown ticket. Hillary should never have run—too much baggage. Just as Jeb Bush was tarred by his brother—so too is hillary tarred by Bill Clintons womanizing.
She will if she takes the Demonrat candidates with her
Even Nixon was convinced to resign
The super delegates are not bound. She has not won enough bound to sew it up. If the unpledged abandon her, she would have to win over 90% of the remaining bound delegates to get the nod. If they want to stop the nomination, they have to do it soon, however.
If Hitlery steps down, she will frog walk in a week.
