Abe Lincoln merely used the antislavery ploy to get more people to join the war cause. He may have very well been racist, but I have no proof. You can never have proof of someone's opinion. And opinions change, too. Who knows what Lincoln was like?
JFK, I believe, does not deserve most of the splendor he receives. I don't know why everyone assumes that the President is responsible for everything that happens in the country. . . he usually just gives the okay, so it's hardly his fault if it fails or his accomplishment if he succeeds. Sure, JFK okayed some okay plans, but he undoubtedly screwed quite a few over as well. The only one I know of offhand was the Bay of Pigs operation. . . something to do with Cuba, I think perhaps a coup d'etat of Castro. Anyway, the CIA botched it and pissed off the Cubans, and I think that was the cause of the Cuban Missile Crisis.
He was an average President at best. . . most of them are.
I hate politics.
