Who were the first presidential candidates to debate on television?

The first presidential candidates to debate on television were John F. Kennedy and Richard Nixon in 1960. This debate marked a significant moment in U.S. political history, as it was the first time that voters could see the candidates face-to-face in a televised format, allowing for a more personal connection and influencing public perception.

Kennedy's charismatic and composed demeanor contrasted with Nixon's appearance and performance, which many viewers found less compelling. This debate showcased the power of television in politics and signaled a shift in how candidates would engage with the electorate going forward. The lasting impact of this event set the stage for future debates and highlighted the importance of media in political campaigns.

The other options represent notable debates in political history but did not introduce the televised format for presidential candidates. The Kennedy-Nixon debate fundamentally transformed the way politics were conducted in America.
