In 2000 and 2004, the outcome of the presidential race was unknown into the wee hours of the morning (and indeed for several weeks thereafter in 2000). This time, it is possible that we will be able to guess the winner of the presidential race relatively early in the evening.

"So Mr Obama’s star quality will be useful to him as president. But that alone is not enough to earn him the job. Charisma will not fix Medicare nor deal with Iran. Can he govern well? Two doubts present themselves: his lack of executive experience; and the suspicion that he is too far to the left.

"There is no getting around the fact that Mr Obama’s résumé is thin for the world’s biggest job. But the exceptionally assured way in which he has run his campaign is a considerable comfort. It is not just that he has more than held his own against Mr McCain in the debates. A man who started with no money and few supporters has out-thought, out-organised and out-fought the two mightiest machines in American politics—the Clintons and the conservative right."
