There's a popular view among Democrats and the media establishment that the reason for the party's current disarray is that it just happens to have two most extraordinary candidates: talented, attractive, and in their gender and race, excitingly new. But there's an alternative explanation, which I suspect the voters have grasped rather better than their necromancers in the media. Both are losers.

But the mask has slipped. Under pressure in a Democratic primary, Mr Obama has sounded just like any other tax-raising, government-loving Democratic politician. Worse, he has revealed himself to be a member of that special subset of the party's liberal elite - a well-educated man with a serious superiority complex.

His worst moment of the campaign was when he was caught telling liberal sophisticates about his anthropological observations on the campaign trail. In the misery of their daily lives, he said, the hicks out there in the sticks cling to religion and guns and the other irrational necessities of the unenlightened life. His wife had earlier told voters that they should be grateful that someone of his protean talents had deigned to come among them and be their president.

The events of the last month have also revealed another side of Mr Obama that threatens to undermine his whole message. He is a cynic. He tells the mavens of San Francisco one thing and the great unwashed of Pennsylvania another. In defending his long relationship with the Rev Jeremiah Wright, he shopped his own grandmother, comparing the reverend's views (God Damn America! The US deliberately spread Aids among the black population) to his grandmother's occasionally expressed fears about the potential of being the victim of crime at the hands of an African-American.

American presidential elections turn as much on the characters of the candidates as they do on the saliency of policies. Democrats, of course, think this is all rather crass. They think voters should confine themselves to the “issues”. But Americans understand their government a little better. They know the limits of presidential office and they understand the president's role as head of state is as much about leadership of the nation as it is about implementation of policy.

What they want is a man - or a woman - of character and record to inspire and lead them. That may be why the Democrats are in trouble.
