The chart is not (and will never be) complete, of course. There are lots of future presidents out there, some of them not named Clinton and Bush. We'll only know whose lives they overlapped with once we know who they are. And the odds are good that none of them will have ever met Barack Obama.

Unless, of course, we are talking about future presidents of Kenya.
