In North Carolina, Obama is up 56-42, by 214,000 votes, with 93 percent reporting.
Hillary won Pennsylvania by 214,000 votes. So, it's gone.
Now, her only gain from the last three large states is whatever she ekes out in Indiana.
Her chances of overtaking Obama in the popular vote -- without a gimmick like Florida, Michigan, or not counting caucus states -- are now almost as long as her chances of overtaking Obama in pledged delegates.
With a popular vote/pledged delegate split, there was a foundation for urging superdelegates to make an assessment of electability and giving her the nomination.
But with no foundation, it's a bigger push to try to get them to overturn both the popular vote and the pledged delegate leader.
