d. He could restore Americans’ faith in their government after Watergate.
Jimmy Carter was elected president in 1976, following the years during which the Watergate scandal had ended Richard Nixon's presidency and deeply damaged the Republican Party's reputation. Carter, who had been Governor of Georgia from 1971 to 1975, was seen as someone different from Washington insiders. He also was a deeply moral man and active in his church as a Sunday School teacher. At the time, that gave him an air of trustworthiness that was welcomed by an electorate who had grown deeply skeptical of government during the Vietnam war era and the Nixon presidency.
