US Presidents are elected by the Electoral College. However, there were six Presidents who served in office without being endorsed by popular vote. Gerald Ford was one of them; he became president after Richard Nixon resigned in 1974, and was not elected at the end of the term. The other part of the question is a trick. George Washington was never elected by popular vote, but he was elected by the Electoral College (like all Presidents) in 1789 and 1792.
FIRST IT WAS NO ONE.. From November 1963 Until January 1965, there was no Vice President of the United States. He was the last President to have to wait for an election to fill the office. Lyndon Johnson did not have a 25th amendment to benefit from and there was then no procedure to make a person Vice President absent a Presidential election where the person would be elected. (the 25th would be ratified in 1965).
