This is a watershed moment in American politics: we have a realistic chance of seeing our first black president. Possible because Obama transcends race, class and, even at times, ideology.
Why is Obama so appealing, even among white Americans? Americans have given the presidency to white, Anglo-Saxon males (with the exception of John F. Kennedy, America's first Catholic president) since the founding of the republic. It took the imbecility of George H. W. Bush to shatter this myth. Never mind that Bush was rich, educated at both Yale and Harvard, and comes from an aristocratic political family - all the ingredients necessary to be a leader - he proved to be incompetent.
Can Obama do any worse?
