Despite Mr Obama being substantively unoriginal when compared to the other candidates on the Democratic left in policy terms; and in spite of a lack of administrative experience (or possibly because of it) he has distinguished himself by appealing to the nobility of the American soul with his polished oratory. He looks and sounds a leader - and not the prosaic technocrat personified by Mrs Clinton. New Hampshire tomorrow appears set to deliver him the momentum required to take the nomination.
And yet the Democrats have never taken the White House in modern times without a southern white Anglo Saxon protestant as candidate, bar John Kennedy - and that was a bitter campaign and result bearing comparison, arguably, even to the Gore/Bush 2000 contest.
Now the party is on the cusp of presenting a candidate widely described in the world’s media as 'half-white' (and Mr Obama's marketing men seem to have decided that is vote winning commentary). Mr Obama is, more precisely, an American Kenyan (via Indonesia) raised mainly by mid-western (Kansas) grandparents in Hawaii. But why confuse matters.
Perhaps mindful of his unusual background, as well as US electoral history, a nascent strategy appears to be an eventual Obama / Edwards ticket. This conclusion of the scribe's sits on the basis of the last Democratic debate in which John Edwards, a Carolinian, sided with Mr Obama and began a move intended to ultimately nudge Mrs Clinton into campaign oblivion.
Still, the scribe uses a model that suggests John McCain would beat that ticket. For sure, this model has never had to weigh such unprecedented Democratic factors before. And there remains the assumption that Mr McCain becomes the Republican nominee. But on that count, at least, it is a stretch to imagine a campaign-broke quasi-preacher, or a liberal New Yorker viewed with antipathy in the south, or another Governor of Massachusetts not liked by his own side there instead.
Nevertheless, the fact remains that a President Obama would be a resounding rejection of what the US has historically decided upon for the White House; and it would indicate a change in racial attitudes and relations, particularly in but not limited to the south, that would be startling in its pace. Audacity of hope, indeed. And give the man his due if he coined that himself.
