What seems more certain, however, is that we are living through a critical moment in history - a convergence of events and political energy probably unequalled since 1968. In some uncanny ways, 1968 and 2008 share a crisis atmosphere. An unpopular war. An unpopular President. A sense of polarization in society. And, finally, a visionary call for change. In 2008, we have a chance for what kids would call a "do-over."
Maybe this time, we'll get it right.
