...letting it die

Looks like the Obama campaign is going to let the Hillary campaign run its course, as it should:

Its campaign quarry finally cornered, the Obama high command gave it space. The Illinois senator was on track to become the first black presidential nominee of a major party and aides produced a small trickle of superdelegate supporters. But there was nary a word about hastening Clinton's departure.

"I think that it would be inappropriate and awkward and wrong for any of us to tell Senator Clinton when it is time for the race to be over," said Missouri Sen. Claire McCaskill, speaking on a campaign-sponsored conference call with reporters.

Of course, I don't want to jinx anything--but the whole tenor of the media has suddenly shifted. Clinton's stock is plummeting. Can it be that we're finally nearing the end?
