Its strange how people remember JFK's Presidency fondly, yet he never really achieved anything of any more significance than most Presidents.
im far from an expert on the subject, but i think history showed he faced more in 3 years than most two-term presidents. but far and above that, his placement in office kick started an iconic shift that led to a prouder nation, as a whole.
i don't know if obama has that same potential, or at least don't believe it as much as others have. but that's the hope and potential he's running towards, and i'd readily support and accept that.
