Definitely Lincoln for the reasons others have set out above. Kennedy's aura today seems to be directly because he was tragically killed so young and became frozen in time.

There's almost 100 years between Lincoln's assassination and Kennedy's election. A lot can happen in a 100 years.
True, though I don't think it would have any affect on JFK being born, but then again, who knows?
