Chief of Party Definition: Leader of the party to which they belong.
Example: Dwight Eisenhower was the head of the Republican Party. As a head of his party, it is his job to use his influence to back party candidates, raise campaign funds, and appoint party official in order to promote the Republican party. Overall, Eisenhower was a successful party leader. He promoted his republican ideals and was able to gain a wide spectrum of support not only from the Republican party, but Democrats were also fairly supportive of him.
Chief Citizen Definition: Representing all of the people of the United States. To properly face the Americans of the U.S.
Example: Eisenhower took the time to right a speech and and face the citizens of the U.S., and present to them his farewell address. His very approach to leadership furthered this impression, at least on the part of those who had access only to the contemporary public record. The impression that he was a passive chief executive president who reigned rather than ruled was engendered both by his approach to organizing the presidency and by the tactics he used to resolve the built-in conflict between what Americans expect from their president in his dual capacity as head of state and principal national political leader.
