According to Alex Koppelman, Salon’s campaign blogger, Obama has pulled down public pledges from 64 superdelegates since Super Tuesday, including promised endorsements from all of North Carolina’s seven Democratic members of Congress. Koppelman says Clinton has received only nine endorsements in the same period.

Since February, superdelegates have been suggesting they will end the Obama-Clinton death match before the Democratic National Convention convenes in August by eventually pledging in a critical mass for one of the candidates. The question has been when: When will the tipping point arrive where enough party heavyweights come to believe one of the candidates has demonstrably earned the right to the nomination? It seems we’re at last coming close to that point.

The recent decision by the Democratic Party not to hold re-votes in Michigan and Florida, which violated party rules by moving up their primary election dates, seriously eroded all winning scenarios painted by the Clinton team in recent weeks.

In addition, formerly avowed neutral Congress people have started stepping up. This week Minnesota senator Amy Klobuchar and Pennsylvania senator Bob Casey both endorsed Obama, telling the Wall Street Journal that they were seeking an end to the increasingly negative primary campaign.

This week, despite the bluster, Hillary may be feeling a lot like she wishes she felt under the sniper fire she has pretended was popping all around her on the tarmac in Bosnia, where YouTube shows her standing around grinning with her daughter and Sinbad and the Bosnian girl with the flowers.
