Could Mr Obama, simply by dint of being black and having lived in Muslim Indonesia for six years as a boy, really change America's international image so easily?
He would get a hero's welcome, of course—but the next president will get that whoever he or she is, simply for not being George Bush and not having made such a hash of Iraq.
Thereafter, America will be judged on its actions, not its words.
For instance, Mr Obama shows no particular sign of being able to reconcile the need to end the occupation of Iraq with the need to avoid the disaster that a power vacuum in the heart of the Middle East would cause.
Tell us more, said many voters in New Hampshire: to that extent, they were right to deny him certain nomination.
Mrs Clinton, however, also has work to do—much more work than simply mentioning “change” a lot. New Hampshire, after all, is a bedrock of Clintonism: had she lost there, she would have been in dire straits in Nevada, which votes on January 19th, and especially in South Carolina, which votes on January 26th, and where around half the Democratic primary electorate is black. Super Tuesday, when 22 states are to vote, might have been her last stand. Now, after this political near-death, she is back where she started—in the lead. One has to hope, however, that she has learnt a few lessons.
These begin with the idea that it is not enough to exude competence and reel off endless policy proposals.
She must learn poetry from Mr Obama, just as he needs to learn prose from her.
She needs to listen to voters, not talk at them.
Above all, she has to shed that sense of wounded entitlement that has bedevilled her campaign; she has to show that the Clintons are not yesterday's people.
Her problem is not just that Mr Obama could still catch her; she has reminded many Americans how divisive a politician she is.
If she wins the primaries, it may be only because core Democratic groups (trade unions, the uneducated, the poor, the old) rallied to her side.
And a nomination does not a president make.
