Jimmy Carter. America's 39th President. Nobel Peace Prize winner. Humanitarian. And today's special guest of our on-going series, "This American Moment." All this week and next, we're asking top thinkers from a variety of backgrounds to put this election in context, and tell us what he or she thinks is at stake. We'll check in with President Carter. We'll ask him about the transformation he's seen from segregation and Jim Crow to the nomination of Senator Obama, and whether he thinks America's role in the world has changed. But we also want you to join the conversation: what does this American moment mean to you?
