IN CARTOONS there is often a moment when a hapless character, having galloped over a cliff, is still unaware of the fact and hangs suspended in the air, legs pumping wildly, until realisation dawns, gravity intervenes and downfall ensues. Hillary Clinton's campaign looks a bit like that this week. After her heavy loss in North Carolina and her barely perceptible victory in Indiana, a state she needed to carry triumphantly, Mrs Clinton's campaign is surely close to its end.

There is one final reason why Mr Obama is almost there. More than any other candidate this year, he has articulated an idea of a nobler America. That is partly because of who he is. When Mr Obama's parents married, in 1960, a union such as theirs, between a white woman and a black man, was illegal in over half of America's states. Now their son stands at the threshold of the White House. But it also has a lot to do with what he says and how he comports himself. Despite considerable provocation, he has never wavered from his commitment to bipartisanship—nor from the idea of America once again engaging with the world. There are severe problems with the details, on which Mr McCain will hopefully push him even further than Mrs Clinton has, but the upside of an Obama presidency remains greater than that of any other candidate.
