I have read some time ago articles about striking historical and even mathematical similarities between Lincoln and Kennedy. I guess these can be found nowadays on the net too. Like most people I have a deep admiration for Kennedy's unique charisma. A similar article trying to draw parallels between Lincoln and Obama didn't quite convince me, though.
W. Bush ended near the bottom of the ranking, of course, where he belongs. The criminal idiot was recorded saying ""There is no such thing as short-term history. I don't think you can possibly get the full breadth of an administration until time has passed.""
He is right - over time I believe he'll be ranked very last.
