Max Fletcher points out something the cable shows should keep front and center:

Currently, according to the popular vote totals at Real Clear Politics, Obama leads Clinton in total votes cast 13,007,968 to 12,415,286 (a margin of 592,682). This total does not include the results from Florida or Michigan. However, it also does not include results from Iowa, Nevada, Washington, and Maine, which have not released popular vote totals.

If you add up the popular vote in all the states that the DNC allowed into the process, here's the current result:

Obama: 13,335,159
Clinton: 12,629,468
(margin: 705,691 votes)

We all know the Clintons' delegate count is very hard to see overcoming Obama's. But the popular vote is in a similar situation. If at the end of it all, one candidate has more delegates and more votes, why is there a question about who won?
