In the 1969 Chappaquiddick incident, the car Kennedy was driving ran off a bridge and plunged into water, resulting in the death of passenger Mary Jo Kopechne. Kennedy pleaded guilty to leaving the scene of an accident and was given a suspended sentence; however, doubts about his account of the accident significantly damaged his chances of ever becoming President of the United States. Kennedy's one run for the office, in the 1980 presidential election, ended in a primary campaign loss to incumbent Democratic President Jimmy Carter. Kennedy was known for his oratorical power, with his 1968 eulogy for his brother Robert and his 1980 Democratic National Convention rallying cry for American liberalism being his best-known moments. Kennedy's heated rhetoric helped lead to the defeat of the 1987 Robert Bork Supreme Court nomination and usher in an era of intense political battles over federal judicial nominations. Kennedy's personal behavior became the subject of public ridicule in the late 1980s and early 1990s, but his 1992 marriage to Victoria Anne Reggie stabilized his life.
