Elected to the House of Representatives in 1946, John F. Kennedy served six undistinguished years before being elected U.S. Senator from Massachusetts in 1952.

In 1956, his eloquence and political skill almost won him the Vice Presidential nomination at the Democratic National Convention. But the nominee, Adlai Stevenson, chose Tennessee Senator Estes Kefauver as his running mate–fortunately for Kennedy.

President Dwight D. Eisenhower, running for re-election, easily beat Stevenson.

Had Kennedy been on the ticket, his Catholicism would have been blamed for the loss. And this would have likely prevented his getting the Presidential nomination in 1960.

In 1957, his book, Profiles in Courage, won the Pulitzer Prize for history.

From 1957 to 1960, Kennedy laid plans for a successful Presidential race.

Many voters thought him too young and inexperienced for such high office. But he used his TV debates with then-Vice President Richard Nixon to calm such fears, transforming himself overnight into a serious contender.

Many Americans identified with Kennedy as they had with film stars. Compared with normally drab politicians, he seemed exciting and glamorous.

Since 1960, for millions of Americans, mere competence in a President isn’t enough; he should be charming and movie-star handsome as well.

But charismatic politicians face the danger of waning enthusiasm.

Many people were growing disillusioned with Kennedy before he died. He had raised hopes that couldn’t be met—especially among blacks.

And many whites bitterly opposed his support of integration, believing that Kennedy was “moving too fast” in changing race relations.

Still, for millions of Americans, Kennedy represented a time of change.

“Let’s get this country moving again” had been his campaign slogan in 1960. He had demanded an end to the non-existent “missile gap” between the United States and Soviet Union.

And he had said that America should create full employment and re-evaluate its policies toward Africa, Latin America and Asia.

His youth, the grace and beauty of his wife and the often-reported antics of his two young children—Caroline and John—added to the atmosphere that change was under way.

But Kennedy was not so committed to reform as many believed:

• As a Senator he had strongly opposed abolishing the Electoral College.
• He never protested the Red-baiting tactics of Senator Joseph R. McCarthy, a frequent dinner guest at the home of his father.
• As President, Kennedy never forgot that he had been elected by a margin of 112,881 votes. He often rationalized his refusal to tackle controversial issues by saying: “We’ll do it after I’m re-elected. So we’d better make damn sure I am re-elected.”
• He thought the United States should recognize “Red” China, but didn’t try to change American foreign policy toward that nation.

Nevertheless, many historians believe that. by vocally supporting civil rights and healthcare for the elderly, Kennedy laid the groundwork for Lyndon Johnson’s legislative victories.

Perhaps no aspect of Kennedy’s Presidency has received closer study than his assassination.

Hundreds of books and thousands of articles have hotly debated whether he was murdered by a lone “nut” or a deadly conspiracy of powerful men.

JFK’s assassination: The moment of impact

The murder has been the subject of two government investigations. The first, by the Warren Commission in 1964, concluded that an embittered ex-Marine and Marxist, Lee Harvey Oswald, acted alone in killing Kennedy.

Similarly, the Commission determined that nightclub owner Jack Ruby had killed Oswald on impulse, and not as the result of a conspiracy.

Millions of disbelieving Americans rejected the Warren Report—and named their own villains:

• The KGB;
• The Mob;
• Anti-Castro Cubans;
• Vice President Lyndon B. Johnson;
• Right-wing businessmen and/or military leaders;
• Fidel Castro.

Each of these groups or persons had reason to hate Kennedy:

• The KGB—for Kennedy’s humiliating the Soviet Union during the Cuban Missile Crisis.
• The Mob—in retaliation for the administration’s crackdown on organized crime.
• Anti-Castro Cubans—for JFK’s refusal to commit American military forces to overthrowing Castro at the Bay of Pigs invasion.
• Lyndon Johnson—lusting for power, he stood to gain the most from Kennedy’s elimination.
• Right-wing businessmen and/or military leaders—for believing that Kennedy had “sold out” the country to the Soviet Union.
• Fidel Castro—knowing the CIA was trying to assassinate or overthrow him, he had reason to respond in kind.

The second investigation, conducted in 1977-79 by the House Assassinations Committee, determined that Oswald and a second, unknown sniper had fired at Kennedy. (Oswald was deemed the assassin; the other man’s shot had missed.)

The Chief Counsel for the Committee, G. Robert Blakey, believed New Orleans Mafia boss Carlos Marcello organized the assassination, owing to his hatred of Robert Kennedy for his war on the crime syndicates.

Still, 53 years after JFK’s assassination, no court-admissible evidence has appeared to convict anyone other than Oswald for the murder.

The impact of Kennedy’s death on popular culture remains great. Millions saw him as a brilliant, courageous hero who had worked his way to the top.

But his sudden and violent end shocked those who believed there was always a happy ending.

If so gifted—and protected—a man as John F. Kennedy could be so suddenly and brutally destroyed, no one else could depend on a secure future.
