Barbara Jordan gave a keynote address at the 1976 Democratic National Convention for which candidate?

Barbara Jordan's keynote address at the 1976 Democratic National Convention was a significant moment in American political history, and it was delivered in support of Jimmy Carter, who was then a candidate for the presidency. Jordan, a prominent figure known for her eloquence and strong leadership, became the first African American woman to deliver a keynote address at a major party convention. Her speech highlighted issues of justice, equality, and the responsibilities of leadership, effectively capturing the spirit of the Democratic Party at that time.

The other candidates listed were not relevant to the 1976 convention; for instance, Walter Mondale served as Carter's vice president, and George McGovern ran for president in 1972, while Bill Clinton was not a prominent figure in the national spotlight until later in the 1990s. Thus, Jordan's address was directly tied to Carter's campaign, making him the correct choice.
