What impact did the timing of Robert F. Kennedy's assassination have on American politics?

After Kennedy's assassination, many world leaders expressed shock and sorrow, some going on television and radio to address their nations. In countries around the world, state premiers and governors and mayors also issued messages expressing shock over the assassination. After JFK’s death, President Johnson told the nation that passing the Civil Rights Act would be the best way to honor Kennedy’s legacy. By July 1964, Johnson and his allies got the act approved. If Kennedy had lived, the debate over the Civil Rights Act would never have occurred during an election year.
