Jimmy Carter was the worst by a long way. Carter was in charge when the economy went down the drain during the late 1970s and he was a weak President. The best of a bad bunch. I have no idea.
JFK would get my vote if he was on the list as being the best President since World War 2. A man who stood for something and he was an independent, free thinking statesman. Modern world leaders are mere puppets of the same Corporate machine. Gone are the days where a leader stands for the people, civil rights and justice for all.
In my opinion LBJ was in on the JFK assassination. Lee Harvey Oswald did not act alone, despite what we have been told. LBJ, the deputy President had everything to gain by the sudden death of JFK. Nixon could not stand that he was cheated of the Presidency by a rigged count in Chicago, Illinois during the 1960 election. The JFK assassination will forever remain a mystery.
