The League of Women Voters sponsored two presidential debates: the first on September 21, and the second on October 28. The second presidential debate is the second most-watched debate in American history. Republican nominee Ronald Reagan participated in both debates. Independent candidate John B. Anderson only participated in the first presidential debate, while Democratic nominee Jimmy Carter only participated in the second presidential debate.
No vice presidential debate was held in 1980. Anderson's running mate Patrick Lucey was the only one who agreed to participate, while Carter's running mate Walter Mondale and Reagan's running mate George H. W. Bush both refused.
