‘The senator said he took a wrong turning on a dark night’: How tragedy at Chappaquiddick ended Ted Kennedy’s run for president

In the realm of American politics, few families have exerted as much power or attracted as much intrigue as the Kennedys. Their narrative, frequently depicted as both motivating and sorrowful, captivated the nation’s attention. By the conclusion of the 1960s, the youngest of the Kennedy siblings, Edward “Ted” Kennedy, seemed ready to continue the family’s political heritage. With President John F. Kennedy and Senator Robert F. Kennedy both having been lost to assassinations, Ted represented the final significant hope for the Kennedy dynasty.

At just 37 years old, Ted Kennedy had already made a name for himself in the U.S. Senate. Charismatic, well-connected, and popular within the Democratic Party, he was widely regarded as a future presidential contender. Many believed it was only a matter of time before he launched a campaign for the White House.

Then arrived a summer evening that altered everything.

On July 18, 1969, Kennedy attended a small social gathering on Chappaquiddick Island, off the coast of Martha’s Vineyard in Massachusetts. The event brought together a group of close friends and political aides who had worked on Robert Kennedy’s 1968 presidential campaign. Among them was 28-year-old Mary Jo Kopechne, a dedicated campaign staffer known for her intelligence and political passion.

Late that evening, Kennedy left the party with Kopechne. He later said that he was driving her to catch a ferry back to the mainland. At some point, Kennedy’s car veered off a narrow wooden bridge without guardrails and plunged into a tidal pond. He managed to escape the sinking vehicle, but Kopechne was trapped inside.

Instead of immediately contacting emergency services, Kennedy walked back to the cottage where the party had taken place. According to his own statement, he discussed the incident with others at the gathering but did not notify the police until the following morning—roughly ten hours later. By that time, Kopechne’s body had been recovered by a diver. She had drowned.

Reports of the mishap circulated quickly, leading to extensive public dismay and bewilderment. Why did Kennedy delay in seeking assistance? Was alcohol a factor? Was there additional information that remained undisclosed to the public?

Kennedy eventually delivered a televised statement explaining his version of events. He claimed that he had taken a wrong turn on the dark, unlit roads and drove off the bridge by mistake. He also expressed deep regret over Kopechne’s death, saying he was overcome with shock and exhaustion after the crash, which led to his delay in reporting it.

Nonetheless, numerous individuals deemed his justification inadequate. The notion that an experienced political personage might depart from an accident site without notifying the authorities—even considering the shock of the incident—brought about significant questions regarding his decision-making and honesty. The public examination was severe, and the media attention was unyielding.

Kennedy admitted to fleeing the site of the crash and was given a two-month suspended sentence. Legally, the impact was minor. Politically, though, the effects endured. Although he stayed in the Senate and remained influential in American politics, his reputation as a prospective president was forever damaged.

The Chappaquiddick incident didn’t end Kennedy’s career, but it dramatically altered its trajectory. Over the next four decades, he became one of the most effective and respected legislators in Congress. He championed key issues such as health care reform, education, civil rights, and immigration. His dedication to public service earned him praise across party lines, and by the time of his death in 2009, he was often referred to as the “Lion of the Senate.”

Still, the question lingered: What if Chappaquiddick had never happened? Could Kennedy have become president? Would he have carried the Kennedy legacy even further?

The tragedy of that night—and the decisions made in its aftermath—remained a defining moment in Kennedy’s life. Supporters argued that he had spent decades trying to make amends through public service, while critics maintained that he had never fully answered for his actions. For many Americans, the incident became symbolic of the complex relationship between power, privilege, and accountability.

Ultimately, the legacy of Ted Kennedy was defined by his legislative successes as well as the unanswered questions surrounding that night in the summer of 1969. The accident on Chappaquiddick Island did not diminish his impact on public affairs, but it permanently changed his public image. It served as a reminder to the nation that political figures, regardless of their esteemed standing, are profoundly human—capable of considerable ambition, substantial influence, and serious errors.
