I have no proof of this, but I presume that Clinton knows the popular vote, and she would have leaked the raw vote totals if she had actually won the popular vote.
She can't let the fact out that she lost the popular vote but won a majority of the delegates. Losing a primary by a hair would be acceptable, but winning the delegate count when she lost the popular vote would just confirm everyone's suspicions about Clinton's political machinations, and that would drive even more people to Bernie.
My hope is that Hillary isn't pushed out too early. Biden-Warren would be a harder ticket to beat. Sanders can't win a general election, and Hillary probably wouldn't win.
I’m pretty sure you are right again. When it comes to corruption; nothing is out of bounds for the clinton machine.
