This is a big week for us Americans to argue about why we argue so much about Abraham Lincoln and John F. Kennedy. The argument, I will argue, is really all about us.
It is ironic and appropriate that the 50th anniversary of Kennedy's assassination arrives on the same week as the 150th anniversary of Lincoln's Gettysburg Address. Long after their deaths, their legacies never seem to get old. That's partly because we keep giving them new interpretations to suit our changing times.
