ON AUGUST 28th, barring some dark manoeuvre by seething Clintonistas, Barack Obama will accept the Democratic nomination for the presidency. Forty-five years to the day after Martin Luther King spoke of his dream, America will take a giant leap towards the realisation of that great call for justice. Hundreds of millions will watch, and be moved; Mr Obama seems to many, by reason of his race, his calm intelligence, his youthful good looks and his powerful oratorical skills, to be well suited to draw a line beneath the bitter Bush years and to repair America’s torn relationship with the outside world. One prominent pundit was much derided earlier this year for describing the tingle he got from listening to the candidate—but everyone knew exactly what he meant.

This moment comes as much through perspiration as through inspiration. Mr Obama’s achievement in defeating the Clinton machine was monumental. Hillary Clinton started out as the overwhelming favourite, with the Democratic Party establishment, not to mention its big-ticket donors, squarely behind her and poll leads that sometimes topped 20 percentage points. But Mr Obama ran a brilliant campaign, using the internet to harness the energy and the donations of an army of volunteers, and deploying them with tactical skill in almost every state. He managed the firestorm touched off by his intemperate pastor, Jeremiah Wright, with dignity and, eventually, ruthlessness.

When it comes to the issues, it is hardly surprising that The Economist is less impressed. Mr Obama’s tilt towards protectionism during the primary campaign was both wrong and dangerous. So was his insistence on denying funds to the “surge” that has worked so well (if belatedly) in Iraq, and his determination to withdraw troops from the conflict according to a rigid timetable. We are nervous about his incentive-destroying willingness to raise taxes sharply on the well-off, and of the cost implications of many of his policies. But we recognise that his positions have evolved as the campaign has moved from the primary stage, where politicians have to outdo each other in their appeal to their party faithful, to the general election. Were he to become president, they would move further to the centre again. And policies are by no means the whole story of an American election: character and leadership matter greatly, too. Mr Obama is an impressive nominee with the potential to be a fine president.
