Despite continuing to lag in pledged delegates, if Hillary can win the popular vote it would create a strong moral argument for boosting her superdelegate support and chances for the nomination. Even that seems like a heavy lift given the remaining primary schedule, but Jay Cost at Real Clear Politics notes that after her win last night, it is not out of the question.

Yet this race is so close and has experienced so many bizarre shifts (e.g. Florida and Michigan issues), "how" you count popular votes now makes a big difference. Real Clear Politics actually tracks six different categories of popular vote. With last night's win, Senator Clinton now leads in two of the six popular vote counts they monitor after adding the net 215,169 votes she picked up last night. Key to this math is adding the Florida and Michigan numbers to her total, which provides her a popular vote margin of 122,728.

And of course, the argument that every vote should be counted is likely to resonate with some Democratic voters.
