Hillary's odds of overtaking Obama among elected delegates are not much better than those of the milk-wagon nag's winning the Preakness. But is it "mathematically impossible" for Clinton to win the nomination? No way. Many superdelegates remain undeclared. And even those who have come out for Obama are not bound. If another shoe of the Rev. Wright variety were to drop, it's far from inconceivable that the supers would move to Hillary.

But perhaps in a sign of how much the MSM wants Hillary out and their guy in, Norah O'Donnell has had the chutzpah to proclaim to Hillary honcho Terry McAuliffe that it is "mathematically impossible" for Clinton to win. At 12:03 PM ET today on MSNBC, O'Donnell began by playing for McAuliffe's benefit a clip from last night of Tim Russert declaring that "we now know who the Democratic nominee is going to be." When McAuliffe denied that the race was over, Norah challenged him.

NORAH O'DONNELL: Yeah, but Terry, Terry, under what scenario, under what possible scenario, could Senator Clinton win this nomination? It is mathematically impossible.

McAuliffe replied by citing the obvious—the game-changing ability of the superdelegates. Surely Norah knows this. So why put pressure on Clinton to get out now? Norah tipped her hand with her next line of questioning.

O'DONNELL: But Terry, there may be some Democrats who may argue about at what cost she continues this battle, in terms of continuing to point out that he's unelectable as your campaign, the senator's campaign, has done.

Norah might not have to look much further than the MSNBC newsroom—or perhaps even in the mirror—to find "some Democrats" worried about the harm Hillary's doing to Obama.
