It should also take a lot of the air out of Bernie Sander's sails as many of his followers are fickle and are still love-struck with Obama and Biden will be immediately accepted as Obama's true successor.
I have a hunch we'll never see Shrillary debate. Biden's entrance and ensuing "surge" in the polls will likely cause her to drop out by end of October.
The Democrat Establishment as in elites and donors will go with Hillary but if she falls down to Sanders Biden will be brought in as the DNCe choice.
The corporate elites run both parties and Sanders is unacceptable to them.
