Politico :

Unless Clinton is able to at least win the primary popular vote — which also would take nothing less than an electoral miracle — and use that achievement to pressure superdelegates, she has only one scenario for victory. An African-American opponent and his backers would be told that, even though he won the contest with voters, the prize is going to someone else.

People who think that scenario is even remotely likely are living on another planet.

The notion of the Democratic contest being a dramatic cliffhanger is a game of make-believe.
Story Behind the Story

The real question is why so many people are playing. The answer has more to do with media psychology than with practical politics.

Journalists have become partners with the Clinton campaign in pretending that the contest is closer than it really is. Most coverage breathlessly portrays the race as a down-to-the-wire sprint between two well-matched candidates, one only slightly better situated than the other to win in August at the national convention in Denver.

Slate :

Clinton can win only by overturning Obama’s pledged delegate lead—a truism that still has not gotten the traction it deserves. Ominous warnings about 1968-like riots aside, the prospect that Clinton would accept the nomination over the head of the people is fundamentally at odds with everything the party represents. She talks about wanting to enfranchise the people of Florida and Michigan. But then, inevitably, she would turn around and seek to revert the people’s decision, expressed through the pledged delegate count. Call me naive, but I find it inconceivable that the party would want this to happen, or that a candidate would want to win that way.

All this being a long way of saying, Hillary’s path to the nomination is not “narrow.” It’s barricaded. Yet still there seems to be a hesitation among the media to declare Clinton dead.

Hans Christian Andersen :

The emperor marched in the procession under the beautiful canopy, and all who saw him in the street and out of the windows exclaimed: “Indeed, the emperor’s new suit is incomparable! What a long train he has! How well it fits him!” Nobody wished to let others know he saw nothing, for then he would have been unfit for his office or too stupid. Never emperor’s clothes were more admired.

“But he has nothing on at all,” said a little child at last. “Good heavens! listen to the voice of an innocent child,” said the father, and one whispered to the other what the child had said. “But he has nothing on at all,” cried at last the whole people. That made a deep impression upon the emperor, for it seemed to him that they were right; but he thought to himself, “Now I must bear up to the end.” And the chamberlains walked with still greater dignity, as if they carried the train which did not exist.
