Senator Robert F. Kennedy stops to sign a photograph of himself for a supporter during the 1968 Presidential Campaign.
Kennedy announced his candidacy for the Democratic presidential nomination in March 1968, after stating in January of that year that he had no plans to challenge incumbent Democratic President Johnson.
In declaring his intent to seek the country's highest office, Kennedy said: "I do not run for the Presidency merely to oppose any man, but to propose new policies. I run because I am convinced that this country is on a perilous course and because I have such strong feelings about what must be done, and I feel that I'm obliged to do all I can." (Bill Eppridge)
