Hillary can't win popular vote

Mathematically speaking, we are now getting to the point where Hillary Clinton's chances of winning the popular vote nationwide -- the only way she can make a good case to super delegates -- is electorally impossible.  She is behind by more than half a million votes:

13,355,239 - Barack Obama
12,637,963 - Hillary Clinton

Real Clear Politics

In Pennsylvania, Clinton can overcome some of that 717,276 vote deficit, but only by about 200,000 at the most.  That would still leave Obama ahead by some half-a-million votes.  And after Pennsylvania, there aren't any other large states left -- with the exception of North Carolina, but Obama is way ahead in the polls there.

Again, is it possible?  Sure.  Is it electorally plausible?  Not at all.
