As I see it....Barack Obama will be remembered largely for his character and integrity, his grace and charm.

Yes, the Affordable Care Act will be mentioned as well, but the measure of this man is his humanity.

Accomplishments in 8 years? Legacy? I can't think of how he has changed the country in any measurable way (sans the ACA) or where his policies and decisions will be remembered as great. His foreign policy decisions get very mixed reviews.

I think JFK did much more to inspire a new generation of Americans, to set us on a course towards civil rights justice under the law. He sent us to the moon, both literally and metaphorically. He averted a potential nuclear war with the Soviets by showing tremendous restraint and brilliant diplomacy during the Cuban Missile Crisis....secured a nuclear test ban treaty with the Soviets.

He launched the Peace Corps which highlighted American exceptionalism. He left office universally respected by all countries, loved by most.

As far as rhetorical skills... JFK is second to none, the texts of his speeches, written in large part by Ted Sorenson, married eloquence and poetry, while never talking over the common man.

JFK was President for less than 3 years...and his footprint is totally disproportionate with that brief blink. Imagine if he had another 4 1/2 years as Obama has had...

My opinions.
