President-elect
From Conservapedia
President-elect is the term used to describe the successful candidate in a US presidential election, between his election and his inauguration, when he formally takes office. In the modern era, many outgoing Presidents have worked with the President-Elect to ensure a smooth transition. However, the President-Elect has no official duties; he is only mentioned in the Twentieth Amendment to the Constitution in the context of what happens if he dies before taking office:
If, at the time fixed for the beginning of the term of thePresident, the President elect shall have died, the Vice President elect
shall become President...
Despite this, President-elect Barack Obama frequently referred to the "Office of the President-Elect"[1]
